<h3>Concatenated database definition files</h3>
<p>Database definition (dbd) files can now be concatenated during the EPICS build
into a created dbd file with the created dbd file then installed into
$(INSTALL_LOCATION)/dbd. The following lines in a Makefile will create a name.dbd
file containing a copy of lines from file1.dbd followed by lines from file2.dbd
then file3.dbd and then install name.dbd into $(INSTALL_LOCATION)/dbd. NO dbd file
expansions will be done.
<blockquote> <pre>
DBDCAT += name.dbd
name_DBD += file1.dbd file2.dbd file3.dbd
</pre></blockquote>
The files file1.dbd, file2.dbd, and file3.dbd will be found if they exist in the
current directory, are created by the current Makefile, have fullpath name ,or
