-Building
---------
-
-Building uses the make utility and the EPICS base build system.
-
-The build system needs the location of the prerequisites, e.g. by placing the
-lines of the form
-
-    PVCOMMON = /home/install/epicsV4/pvCommonCPP
-    EPICS_BASE = /home/install/epics/base
-
-pointing to the locations in a file called RELEASE.local
-in the configure directory or the parent directory of pvDataCPP.
-
-With this in place, to build type make
-
-    make
-
-To perform a clean build type
-
-    make clean uninstall
-
-To run the unit tests type
-
-    make runtests
-
-For more information on the EPICS build system consult the
-[Application Development guide](http://www.aps.anl.gov/epics/base/R3-14/12-docs/AppDevGuide.pdf).
