There are many tools for windows to audit installed programs. You
might be better served using them conduct audits of installed programs
(and their versions).
There are probably even some programs around that can grab the version
details from an EXE file (I believe it's a fairly standard MS format).
You could use such a program (or write one) to get the TSVN proc exe
I understand the problem of TSVN and svn getting out of sync ---
either can silently upgrade working copies that will then no longer
work with the other client.
However, your case seems to be an issue of wanting to use a program to
fix problems of people not following procedures. If you tell your
people to NOT install new versions, and they do, yell at them. If
they keep doing it, fire them.
Alternatively, lock down the computers so that users can not do those
things. NOTE: even if you lock down the computer, a user could still
unpack an svn-win32*.zip distribution into his path.
Locking down the computers rarely solves as many problems as it creates.
Threating to not use TSVN if the problems aren't fixed to your
satisfaction, is probably not very helpful.
That said, some of the items you mentioned (having the /version
qualifier) could provide some benefits (e.g. sanity checking in
scripts) and not interfere with other TSVN functions.
Another possibility for the TSVN team: since it is so common to want
both TSVN and the SVN command line clients, perhaps TSVN could, as an
option, be bundled with the svn command line clients (and SVN Book)
and thus share all the libraries, config files, etc... from one
install? I'm not sure how much work that would be to add, but it has
the potential of preempting many of these problems. It may just be
more of a headache than anything else. The only real difficulty I've
seen in keeping TSVN and SVN in sync is that TSVN releases new builds
faster than the SVN group get their Windows install files up. You can
still use the zip files though.
