No, I hadn't even though I've used them once in the past for incorporating
3rd party code into another project. I'm still new to subversion and I
appreciate you making that point. After rereading the external section of
the book, does svn 1.4 support external definitions for files now? I didn't
see anything about it in the release notes or changes file. If so, that
would seem to resolve my issue.

Here's an example:



All files in directory_one and directory_two are exactly the same. Files
within their subdirectories, reports/ and config/, are different.

Physically, directory_one and directory_two are equivalent applications with
just different config files and different report files. Logically, they are
two separate applications.

My eventual goal is to move the bifurcation from the config/ and report/
directories and into the application to simplify deployment of the whole
application and maintenance of the reports. The reports' formats are the
same between directory_one/report and directory_two/report. The only
difference is that reports in directory_one connect to one data source and
reports in directory_two connect to another one.
