Okay - I think I understand. If I have 'dirs.orig' pointing to the global
area, and dirs.local pointing to the local modified area, and want to put
the file into 'dest', I can do the following:
<property name="frompath" value="${dirs.orig}/foo"/>
<available file="${dirs.local}/foo" property="frompath"
value="${dirs.local}/foo"/>
<copy file="${frompath}" todir="${dirs.base}/dest"/>
The first line sets the default to the orig directory; the second line
overrides the value of 'frompath' if there exists a file in the .local
directory, and the last line does the copy with whatever the value of the
variable happens to be.
(This is still a little more work than I indended, but I guess that's why
there's Perl/Awk to add these lines into my customizations on build.xml.)
Thanks for the help,
Russ
