Re: Arch (Re: Subversion, SCons, and reorganizationalizing)

I've been looking more at arch and subversion's documentation.
Arch has some nice features, like the simple repository format and good merging.
However, subversion has much better documentation, a usable command line syntax,
and a more portable architecture. Arch may have these in the future, but
subversion has them now.

That said, I won't mind switching to a different version control later, such
as when arch matures more.

I'll get a subversion server set up at https://navi.picogui.org/svn soon.
It should have enough bandwidth for now, and set up a cron script for doing
off-site backups to sourceforge.
