-# Variable expansion
+# Template variable expansion
+
+# This feature allows you to instantiate simple template files at
+# build-time, replacing macros spelled @NAME@ with values provided
+# by the Makefile. The template filename must end with an @ sign,
+# which is removed to create the expanded filename.
+
+# Makefiles can use this variable expansion as follows:
+#
+# 1. Add the template filename (with the trailing @ sign) to either
+#    the EXPAND or EXPAND_COMMON variable, for example:
+#        EXPAND_COMMON += myVersion.h@
+#    Use EXPAND_COMMON for templates that don't depend on the
+#    target architecture (these will be generated in O.Common).
+# 2. There are 2 ways of defining template macros. The simplest
+#    is to add a NAME=VALUE string to the EXPAND_VARS variable for
+#    the desired macros, e.g.:
+#        EXPAND_VARS += MY_MAJOR_VERSION=$(MY_MAJOR_VERSION)
+#        EXPAND_VARS += MY_MINOR_VERSION=$(MY_MINOR_VERSION)
+#    These values may not contain spaces, even if inside quotes.
+# 3. A better way in the above case is to add the names of any
+#    Makefile variables that should be provided as macros to the
+#    variable EXPAND_ME, like this:
+#        EXPAND_ME += MY_MAJOR_VERSION
+#        EXPAND_ME += MY_MINOR_VERSION
+#    The values of these variables may contain spaces.
+# 4. The macros TOP and ARCH will be set by the build system.
+#    TOP is the value of $(INSTALL_LOCATION) for this module.
+#    ARCH is the target architecture $(T_A), but is only set
+#    while expanding files in EXPAND
+# 5. Add the expanded filename to some other variable that will
+#    cause it to be created and used, such as INC here:

-  What is EPICS base?
-
-     The Experimental Physics and Industrial Control Systems (EPICS) is an
-     extensible set of software components and tools with which application
-     developers can create a control system. This control system can be used
-     to control accelerators, detectors, telescopes, or other scientific
-     experimental equipment. EPICS base is the set of core software, i.e. the
-     components of EPICS without which EPICS would not function. EPICS base
-     allows an arbitrary number of target systems, IOCs (input/output
-     controllers), and host systems, OPIs (operator interfaces) of various
-     types.
-
-  What is new in this release?
-
-     Please check the RELEASE_NOTES file in the distribution for description
-     of changes and release migration details.
-
-  Copyright
-
-     Please review the LICENSE file included in the distribution for legal
-     terms of usage.
-
-  Supported platforms
-
-     The list of platforms supported by this version of EPICS base is given
-     in the configure/CONFIG_SITE file. If you are trying to build EPICS Base
-     on an unlisted host or for a different target machine you must have the
-     proper host/target cross compiler and header files, and you will have to
-     create and add the appropriate new configure files to the
-     base/configure/os/directory. You can start by copying existing
-     configuration files in the configure/os directory and then make changes
-     for your new platforms.
-
-  Supported compilers
-
-     This version of EPICS base has been built and tested using the host
-     vendor's C and C++ compilers, as well as the GNU gcc and g++ compilers.
-     The GNU cross-compilers work for all cross-compiled targets. You may
-     need the C and C++ compilers to be in your search path to do EPICS
-     builds; check the definitions of CC and CCC in
-     base/configure/os/CONFIG.<host>.<host> if you have problems.
-
-  Software requirements
-
-     GNU make
-     You must use the GNU version of make for EPICS builds, and we now
-     recommend version 4.1 or later (version 3.82 may work on Linux, but
-     doesn't on Windows).
-
-     Perl
-     You must have Perl version 5.8.1 or later installed. The EPICS
-     configuration files do not specify the perl full pathname, so the perl
-     executable must be found through your normal search path.
-
-     Unzip and tar (Winzip on WIN32 systems)
-     You must have tools available to unzip and untar the EPICS base
-     distribution file.
-
-     Target systems
-     EPICS supports IOCs running on embedded platforms such as VxWorks and
-     RTEMS built using a cross-compiler, and also supports soft IOCs running
-     as processes on the host platform.
-
-     vxWorks
-     You must have vxWorks 6 installed if any of your target systems are
-     vxWorks systems; the C++ compilers for vxWorks 5.x are now too old to
-     support. The vxWorks installation provides the cross-compiler and header
-     files needed to build for these targets. The absolute path to and the
-     version number of the vxWorks installation must be set in the
-     base/configure/os/CONFIG_SITE.Common.vxWorksCommon file or in one of its
-     target-specific overrides.
-
-     Consult the vxWorks 6.x EPICS web pages and the vxWorks documentation
-     for information about configuring your vxWorks operating system for use
-     with EPICS.
-
-     RTEMS
-     For RTEMS targets, you need RTEMS core and toolset version 4.9.2 or
-     4.10. The newer 4.11 or 5.x releases are not supported yet.
-
-     Command-line editing libraries
-     GNU readline or other OS-specific libraries can be used by the IOC shell
-     to provide command line editing and history recall. The default setting
-     is different for each OS. On Linux the default is to use READLINE since
-     most distributions include it. On MacOS the default is also READLINE
-     since Apple provides a compatible library, although it isn't GNU. On
-     RTEMS we support GNU readline and Tecla, although the default is to use
-     neither since these have to be added to the RTEMS installation
-     separately. On vxWorks we support the built-in ledLib library.
-
-  Host system storage requirements
-
-     The compressed tar file is approximately 1.6 MB in size. The
-     distribution source tree takes up approximately 12 MB. Each host target
-     will need around 40 MB for build files, and each cross-compiled target
-     around 20 MB.
-
-  Documentation
-
-     EPICS documentation is available through the EPICS website at Argonne.
-
-     Release specific documentation can also be found in the
-     base/documentation directory of the distribution.

-
-  Building EPICS base (Unix and Win32)
-
-    Unpack file
-
-       Unzip and untar the distribution file. Use WinZip on Windows systems.
-
-    Set environment variables
-
-       Files in the base/startup directory have been provided to help set
-       required path and other environment variables.
-
-       EPICS_HOST_ARCH
-       Before you can build or use EPICS Base, the environment variable
-       EPICS_HOST_ARCH should be defined. A perl script EpicsHostArch.pl in
-       the base/startup directory has been provided to help set
-       EPICS_HOST_ARCH. You should have EPICS_HOST_ARCH set to your host
-       operating system followed by a dash and then your CPU architecture,
-       e.g. linux-x86_64. If you are not using the OS vendor's c/c++ compiler
-       for host builds, you will need another dash followed by the alternate
-       compiler name (e.g. "-gnu" for GNU c/c++ compilers on a solaris host
-       or "-mingw" for MinGW c/c++ compilers on a WIN32 host). See
-       configure/CONFIG_SITE for a list of supported EPICS_HOST_ARCH values.
-
-       PERLLIB
-       On WIN32, some versions of Perl require that the environment variable
-       PERLLIB be set to <perl directory location>.
-
-       PATH
-       As already mentioned, you must have the perl executable and you may
-       need C and C++ compilers in your search path. For building base you
-       also must have echo in your search path. For Unix host builds you also
-       need ln, cpp, cp, rm, mv, and mkdir in your search path and /bin/chmod
-       must exist. On some Unix systems you may also need ar and ranlib in
-       your path, and the C compiler may require as and ld in your path. On
-       solaris systems you need uname in your path.
-
-       LD_LIBRARY_PATH
-       EPICS shared libraries and executables normally contain the full path
-       to any libraries they require. However, if you move the EPICS files or
-       directories from their build-time location then in order for the
-       shared libraries to be found at runtime LD_LIBRARY_PATH must include
-       the full pathname to $(INSTALL_LOCATION)/lib/$(EPICS_HOST_ARCH) when
-       invoking executables, or some equivalent OS-specific mechanism (such
-       as /etc/ld.so.conf on Linux) must be used. Shared libraries are now
-       built by default on all Unix type hosts.
-
-    Do site-specific build configuration
-
-       Site configuration
-       To configure EPICS, you may want to modify the default definitions in
-       the following files:
-
-         configure/CONFIG_SITE      Build choices. Specify target archs.
-         configure/CONFIG_SITE_ENV  Environment variable defaults
-         configure/RELEASE          TORNADO2 full path location
-
-       Host configuration
-       To configure each host system, you may override the default
-       definitions by adding a new file in the configure/os directory with
-       override definitions. The new file should have the same name as the
-       distribution file to be overridden except with CONFIG in the name
-       changed to CONFIG_SITE.
-
-         configure/os/CONFIG.<host>.<host>      Host build settings
-         configure/os/CONFIG.<host>.Common      Host common build settings
-
-       Target configuration
-       To configure each target system, you may override the default
-       definitions by adding a new file in the configure/os directory with
-       override definitions. The new file should have the same name as the
-       distribution file to be overridden except with CONFIG in the name
-       replaced by CONFIG_SITE. This step is necessary even if the host
-       system is the only target system.
-
-         configure/os/CONFIG.Common.<target>     Target common settings
-         configure/os/CONFIG.<host>.<target>     Host-target settings
-
-    Build EPICS base
-
-       After configuring the build you should be able to build EPICS base by
-       issuing the following commands in the distribution's root directory
-       (base):
-
-         gnumake clean uninstall
-         gnumake
-
-       The command "gnumake clean uninstall" will remove all files and
-       directories generated by a previous build. The command "gnumake" will
-       build and install everything for the configured host and targets.
-
-       It is recommended that you do a "gnumake clean uninstall" at the root
-       directory of an EPICS directory structure before each complete rebuild
-       to ensure that all components will be rebuilt.
-
-  Example application and extension
-
-     A perl tool, makeBaseApp.pl is included in the distribution file. This
-     script will create a sample application that can be built and then
-     executed to try out this release of base.
-
-     Instructions for building and executing the example IOC application can
-     be found in the section "Example Application" of Chapter 2, "Getting
-     Started", in the "IOC Application Developer's Guide" for this release.
-     The "Example IOC Application" section briefly explains how to create and
-     build an example application in a user created <top> directory. It also
-     explains how to run the example application on a vxWorks ioc or as a
-     process on the host system. By running the example application as a
-     host-based IOC, you will be able to quickly implement a complete EPICS
-     system and be able to run channel access clients on the host system.
-
-     A perl script, makeBaseExt.pl, is included in the distribution file.
-     This script will create a sample extension that can be built and
-     executed. The makeBaseApp.pl and makeBaseExt.pl scripts are installed
-     into the install location bin/<hostarch> directory during the base
-     build.
-
-  Multiple host platforms
-
-     You can build using a single EPICS directory structure on multiple host
-     systems and for multiple cross target systems. The intermediate and
-     binary files generated by the build will be created in separate
-     subdirectories and installed into the appropriate separate host/target
-     install directories. EPICS executables and perl scripts are installed
-     into the $(INSTALL_LOCATION)/bin/<arch> directories. Libraries are
-     installed into $(INSTALL_LOCATION)/lib/<arch>. The default definition
-     for $(INSTALL_LOCATION) is $(TOP) which is the root directory in the
-     distribution directory structure, base. Created object files are stored
-     in O.<arch> source subdirectories, This allows objects for multiple
-     cross target architectures to be maintained at the same time. To build
-     EPICS base for a specific host/target combination you must have the
-     proper host/target C/C++ cross compiler and target header files and the
-     base/configure/os directory must have the appropriate configure files.

-<BLOCKQUOTE>The Experimental Physics and Industrial Control Systems
- (EPICS) is an extensible set of software components and tools with
- which application developers can create a control system. This control
- system can be used to control accelerators, detectors, telescopes, or
- other scientific experimental equipment. EPICS base is the set of core
- software, i.e. the components of EPICS without which EPICS would not
- function. EPICS base allows an arbitrary number of target systems, IOCs
- (input/output controllers), and host systems, OPIs (operator
- interfaces) of various types.</BLOCKQUOTE>

- Before you can build or use EPICS Base, the environment variable
- EPICS_HOST_ARCH should be defined. A perl script EpicsHostArch.pl in the
- base/startup directory has been provided to help set EPICS_HOST_ARCH.
- You should have EPICS_HOST_ARCH set to your host operating system
- followed by a dash and then your CPU architecture, e.g. linux-x86_64.
- If you are not using the OS vendor's c/c++ compiler for host builds,
- you will need another dash followed by the alternate compiler name
- (e.g. &quot;-gnu&quot; for GNU c/c++ compilers on a solaris host or &quot;-mingw&quot;
- for MinGW c/c++ compilers on a WIN32 host). See configure/CONFIG_SITE
- for a list of supported EPICS_HOST_ARCH values.</P>
-
-<P><B>PERLLIB</B><BR>
- On WIN32, some versions of Perl require that the environment
- variable PERLLIB be set to &lt;perl directory location&gt;.</P>
-
-<P><B>PATH</B><BR>
- As already mentioned, you must have the perl executable and you may
- need C and C++ compilers in your search path. For building base you
- also must have echo in your search path. For Unix host builds you also
- need ln, cpp, cp, rm, mv, and mkdir in your search path and /bin/chmod
- must exist. On some Unix systems you may also need ar and ranlib in
- your path, and the C compiler may require as and ld in your path. On
- solaris systems you need uname in your path.</P>
-
-<P><B>LD_LIBRARY_PATH</B><BR>
-
- EPICS shared libraries and executables normally contain the full path
- to any libraries they require.
- However, if you move the EPICS files or directories from their build-time
- location then in order for the shared libraries to be found at runtime
- LD_LIBRARY_PATH must include the full pathname to

- <PRE>
-        gnumake clean uninstall
-        gnumake
-</PRE>
-
- The command &quot;gnumake clean uninstall&quot;
- will remove all files and directories generated by a previous build.
- The command &quot;gnumake&quot; will build and install everything for the

- Instructions for building and executing the example IOC application
- can be found in the section &quot;Example Application&quot; of Chapter 2,
- &quot;Getting Started&quot;, in the &quot;IOC Application Developer's Guide&quot; for this
- release. The &quot;Example IOC Application&quot; section briefly explains how to
- create and build an example application in a user created &lt;top&gt;
- directory. It also explains how to run the example application on a
- vxWorks ioc or as a process on the host system.
- By running the example application as a host-based IOC, you will be
- able to quickly implement a complete EPICS system and be able to run channel
- access clients on the host system.
-
-<P>
- A perl script,
- makeBaseExt.pl, is included in the distribution file. This script will
- create a sample extension that can be built and executed. The
- makeBaseApp.pl and makeBaseExt.pl scripts are installed into the
- install location bin/&lt;hostarch&gt; directory during the base build.

-
-<H3><A NAME="0_0_14"> Multiple host platforms</A></H3>
-<BLOCKQUOTE>You can build using a single EPICS directory structure on
- multiple host systems and for multiple cross target systems. The
- intermediate and binary files generated by the build will be created in
- separate subdirectories and installed into the appropriate separate
- host/target install directories. EPICS executables and perl scripts are
- installed into the <TT>$(INSTALL_LOCATION)/bin/&lt;arch&gt;</TT> directories.
- Libraries are installed into $<TT>(INSTALL_LOCATION)/lib/&lt;arch&gt;</TT>.
- The default definition for <TT>$(INSTALL_LOCATION)</TT> is <TT>$(TOP)</TT>
- which is the root directory in the distribution directory structure,
- base. Created object files are stored in O.&lt;arch&gt; source
- subdirectories, This allows objects for multiple cross target
- architectures to be maintained at the same time. To build EPICS base
- for a specific host/target combination you must have the proper
- host/target C/C++ cross compiler and target header files and the
- base/configure/os directory must have the appropriate configure files.

+### <span id="0_0_1">What is EPICS base?</span>
+
+The Experimental Physics and Industrial Control Systems (EPICS) is an
+extensible set of software components and tools with which application
+developers can create a control system. This control system can be
+used to control accelerators, detectors, telescopes, or other
+scientific experimental equipment. EPICS base is the set of core
+software, i.e. the components of EPICS without which EPICS would not
+function. EPICS base allows an arbitrary number of target systems,
+IOCs (input/output controllers), and host systems, OPIs (operator
+interfaces) of various types.
+
+### <span id="0_0_2">What is new in this release?</span>
+
+Please check the `RELEASE_NOTES` file in the distribution for
+description of changes and release migration details.
+
+### <span id="0_0_3">Copyright</span>
+
+Please review the LICENSE file included in the distribution for legal
+terms of usage.
+
+### <span id="0_0_4">Supported platforms</span>
+
+The list of platforms supported by this version of EPICS base is given
+in the `configure/CONFIG_SITE` file. If you are trying to build EPICS
+Base on an unlisted host or for a different target machine you must
+have the proper host/target cross compiler and header files, and you
+will have to create and add the appropriate new configure files to the
+base/configure/os/directory. You can start by copying existing
+configuration files in the configure/os directory and then make
+changes for your new platforms.
+
+### <span id="0_0_5">Supported compilers</span>
+
+This version of EPICS base has been built and tested using the host
+vendor's C and C++ compilers, as well as the GNU gcc and g++
+compilers. The GNU cross-compilers work for all cross-compiled
+targets. You may need the C and C++ compilers to be in your search
+path to do EPICS builds; check the definitions of CC and CCC in
+`base/configure/os/CONFIG.<host>.<host>` if you have problems.
+
+### <span id="0_0_6">Software requirements</span>
+
+**GNU make**
+You must use GNU make, gnumake, for any EPICS builds. Set your path so
+that a gnumake version 3.81 or later is available.
+
+**Perl**
+You must have Perl version 5.8.1 or later installed. The EPICS
+configuration files do not specify the perl full pathname, so the perl
+executable must be found through your normal search path.
+
+**Unzip and tar (Winzip on WIN32 systems)**
+You must have tools available to unzip and untar the EPICS base
+distribution file.
+
+**Target systems**
+EPICS supports IOCs running on embedded platforms such as VxWorks and
+RTEMS built using a cross-compiler, and also supports soft IOCs
+running as processes on the host platform.
+
+**vxWorks**
+You must have vxWorks 6.8 or later installed if any of your target
+systems are vxWorks systems; the C++ compiler from older versions cannot
+compile recently developed code. The vxWorks installation provides the
+cross-compiler and header files needed to build for these targets. The
+absolute path to and the version number of the vxWorks installation
+must be set in the `base/configure/os/CONFIG_SITE.Common.vxWorksCommon`
+file or in one of its target-specific overrides.
+
+Consult the [vxWorks 6.x](https://epics.anl.gov/base/vxWorks6.php) EPICS
+web pages about and the vxWorks documentation for information about
+configuring your vxWorks operating system for use with EPICS.
+
+**RTEMS**
+For RTEMS targets, you need RTEMS core and toolset version 4.9.x or
+4.10.x (4.11 or 5.x are not yet supported).
+
+**GNU readline or Tecla library**
+GNU readline and Tecla libraries can be used by the IOC shell to
+provide command line editing and command line history recall and edit.
+GNU readline (or Tecla library) must be installed on your target
+system when `COMMANDLINE_LIBRARY` is set to READLINE (or TECLA) for
+that target. EPICS (EPICS shell) is the default specified in
+`CONFIG_COMMON`. A READLINE override is defined for linux-x86 in the
+EPICS distribution. Comment out `COMMANDLINE_LIBRARY=READLINE` in
+`configure/os/CONFIG_SITE.Common.linux-x86` if readline is not
+installed on linux-x86. Command-line editing and history will then be
+those supplied by the os. On vxWorks the ledLib command-line input
+library is used instead.
+
+### <span id="0_0_7">Host system storage requirements</span>
+
+The compressed tar file is approximately 1.6 MB in size. The
+distribution source tree takes up approximately 12 MB. Each host
+target will need around 40 MB for build files, and each cross-compiled
+target around 20 MB.
+
+### <span id="0_0_8">Documentation</span>
+
+EPICS documentation is available through the [EPICS
+website](https://epics.anl.gov/) at Argonne.
+
+Release specific documentation can also be found in the
+base/documentation directory of the distribution.
+
+### <span id="0_0_10">Directory Structure</span>

+### <span id="0_0_12">Building EPICS base (Unix and Win32)</span>
+
+#### Unpack file
+
+Unzip and untar the distribution file. Use WinZip on Windows
+systems.
+
+#### Set environment variables
+
+Files in the base/startup directory have been provided to help set
+required path and other environment variables.
+
+* `EPICS_HOST_ARCH`
+Before you can build or use this EPICS base, the environment variable
+`EPICS_HOST_ARCH` must be defined. A perl script EpicsHostArch.pl in
+the base/startup directory has been provided to help set
+`EPICS_HOST_ARCH.` You should have `EPICS_HOST_ARCH` set to your
+host operating system followed by a dash and then your host
+architecture, e.g. solaris-sparc. If you are not using the OS
+vendor's c/c++ compiler for host builds, you will need another dash
+followed by the alternate compiler name (e.g. "-gnu" for GNU c/c++
+compilers on a solaris host or "-mingw" for MinGW c/c++ compilers on
+a WIN32 host). See `configure/CONFIG_SITE` for a list of supported
+`EPICS_HOST_ARCH` values.
+
+* `PERLLIB`
+On WIN32, some versions of Perl require that the environment
+variable PERLLIB be set to &lt;perl directory location>.
+
+* `PATH`
+As already mentioned, you must have the perl executable and you may
+need C and C++ compilers in your search path. For building base you
+also must have echo in your search path. For Unix host builds you
+also need ln, cpp, cp, rm, mv, and mkdir in your search path and
+/bin/chmod must exist. On some Unix systems you may also need ar and
+ranlib in your path, and the C compiler may require as and ld in
+your path. On solaris systems you need uname in your path.
+
+* `LD_LIBRARY_PATH`
+EPICS shared libraries and executables normally contain the full
+path to any libraries they require. However, if you move the EPICS
+files or directories from their build-time location then in order
+for the shared libraries to be found at runtime `LD_LIBRARY_PATH`
+must include the full pathname to
+`$(INSTALL_LOCATION)/lib/$(EPICS_HOST_ARCH)` when invoking
+executables, or some equivalent OS-specific mechanism (such as
+/etc/ld.so.conf on Linux) must be used. Shared libraries are now
+built by default on all Unix type hosts.
+
+#### Do site-specific build configuration
+
+**Site configuration**
+To configure EPICS, you may want to modify the default definitions
+in the following files:
+
+```
+        configure/CONFIG_SITE      Build choices. Specify target archs.
+        configure/CONFIG_SITE_ENV  Environment variable defaults
+        configure/RELEASE          TORNADO2 full path location
+```
+
+**Host configuration**
+To configure each host system, you may override the default
+definitions by adding a new file in the configure/os directory with
+override definitions. The new file should have the same name as the
+distribution file to be overridden except with CONFIG in the name
+changed to `CONFIG_SITE`.
+
+```
+        configure/os/CONFIG.<host>.<host>      Host build settings
+        configure/os/CONFIG.<host>.Common      Host common build settings
+```
+
+**Target configuration**
+To configure each target system, you may override the default
+definitions by adding a new file in the configure/os directory with
+override definitions. The new file should have the same name as the
+distribution file to be overridden except with CONFIG in the name
+replaced by `CONFIG_SITE`. This step is necessary even if the host
+system is the only target system.
+
+```
+        configure/os/CONFIG.Common.<target>     Target common settings
+        configure/os/CONFIG.<host>.<target>     Host-target settings
+```
+
+#### Build EPICS base
+
+After configuring the build you should be able to build EPICS base
+by issuing the following commands in the distribution's root
+directory (base):
+
+```
+        gnumake clean uninstall
+        gnumake
+```
+
+The command "gnumake clean uninstall" will remove all files and
+directories generated by a previous build. The command "gnumake"
+will build and install everything for the configured host and
+targets.
+
+It is recommended that you do a "gnumake clean uninstall" at the
+root directory of an EPICS directory structure before each complete
+rebuild to ensure that all components will be rebuilt.
+
+### <span id="0_0_13">Example application and extension</span>
+
+A perl tool, makeBaseApp.pl is included in the distribution file. This
+script will create a sample application that can be built and then
+executed to try out this release of base.
+
+Instructions for building and executing the EPICS example application
+can be found in the section "Example Application" of Chapter 2,
+"Getting Started", in the "EPICS Application Developer's Guide". 
+The "Example IOC Application" section briefly explains how to
+create and build an example application in a user created &lt;top>
+directory. It also explains how to run the example application on a
+vxWorks ioc or as a process on the host system. By running the example
+application as a host-based IOC, you will be able to quickly implement
+a complete EPICS system and be able to run channel access clients on
+the host system.
+
+A perl script, makeBaseExt.pl, is included in the distribution file.
+This script will create a sample extension that can be built and
+executed. The makeBaseApp.pl and makeBaseExt.pl scripts are installed
+into the install location `bin/<hostarch>` directory during the base
+build.
+
+### <span id="0_0_14">Multiple host platforms</span>
+
+You can build using a single EPICS directory structure on multiple
+host systems and for multiple cross target systems. The intermediate
+and binary files generated by the build will be created in separate
+subdirectories and installed into the appropriate separate host/target
+install directories. EPICS executables and perl scripts are installed
+into the `$(INSTALL_LOCATION)/bin/<arch>` directories. Libraries are
+installed into $`(INSTALL_LOCATION)/lib/<arch>`. The default
+definition for `$(INSTALL_LOCATION)` is `$(TOP)` which is the root
+directory in the distribution directory structure, base. Created
+object files are stored in `O.<arch>` source subdirectories, This
+allows objects for multiple cross target architectures to be
+maintained at the same time. To build EPICS base for a specific
+host/target combination you must have the proper host/target C/C++
+cross compiler and target header files and the base/configure/os
+directory must have the appropriate configure files.
