Or, if you actually want a pristine working copy with no local edits
left in place:
rm -rf $dir
svn co $URL $dir
I once had a fascinating discussion of a unique local source control
and build system that had been working for some time, but did repeated
"updates" and checkouts that simply did not do what the author thought
it did. Since the system would look for any files with certain
suffixes and process them, neither 'update' nor 'checkout' would be
sufficient to make sure any local config files were cleared. And in
the cases above, neither would clear any files excluded by
This led to some confusion.
