Update on my quest for The Holy Grail.

I ran into some immediate problems with version-ing the entire system.

1. Subversion does not take UNIX pipes! I have read many posts (as far
back as version 1.1.4), and in 2.3.2 pipes still aren't supported. Will
they ever be? Though it is useful for a small number of people, should
subversion set a policy about what type of files can be checked in?

2. Subversion does not keep track of ownership or permissions. This
seems like a killer. I'll need a script that can record all ownership
and permissions on every file before check in. I will also need a
script to read this meta data and fix all the ownership and permissions
after the checkout. This seems like a very big harry task. No?

3. Some files can't be converted to UTF8. I don't really know why svn
wants to convert my source files, but this stops the import cold. I
haven't found the solution for this yet, but I'm still looking.

If there are more pitfalls, please let me know. I'm discovering a few,
but I'm sure I haven't touched on all the issues yet.
