Yeah, I figured it's not the greatest idea, but moving it involves changing
settings on that machine and the systems (plural!) it backs up to. The other
problem, and I can hear people scream in terror now, is that I'm a small
business and can't afford more computers, so this is the computer the system
actually runs on. I have to edit the code on the working, production model.
The system needs certain databases, as well as expensive modems to work
properly, as well as access to dial-in systems. I simply CANNOT afford one
production system and one "working copy" system. I tried that for several
months and the little things like swapping the phone lines, changing times
when one was allowed online and one wasn't almost drove me insane. It was
also almost impossible to keep them synced in terms of data and needed logs,
since I could not use a scheduled backup like rsync, since it would often
overwrite files I was working with.

It's a small business, I get to finish code when I consider it finished (not
on deadline), and do it my way, but I just don't have the funds and/or time
to do everything the way some would want it done. I have a budget, and it
has to pay for the computers and food and rent and heating... I'm also
working 16-20 hours a day, so taking time to alter my setup for backups so I
can do things Subversion's way is not something I relish doing.

I'm not fighting you -- just pointing out there are many things that can limit
our situations or setups.

Actually, that's what I've done. I have /thresh/threshNet/source for SVN,
and /thresh/threshNet/bin (and config, docs, help, data....) for the program.
The source directory is ignored. This way my backup programs get the
repository as well as the entire system in one swell foop.

I didn't realize or understand this, and it is an issue for me. I'm the only
one working on this, and will likely be the only one working on it until I
can afford employees (at that point I'll have test systems for development
and lots of other "nice" things). I've developed it over several years, as I
learned more about programming (I had a class in Assembler in the 1980s, but
am self taught otherwise). I only recently learned what an IDE is, and am
not using one because it's too damned hard to change everything in my setup,
which works well for me, into what an IDE wants me to have.

I may seriously just drop using Subversion, or use it only for the client
system, which does have a development directory tree and a working tree for
testing.
