Ease up there Tom. My understanding of what Brandon said is that he ran
into a limitation of his *shell*, not of arch or perforce.

My understanding of what Brandon said here (and *please* correct me if
I'm wrong) is that Subversion allows you to recursively import a whole
directory tree in one command like this:
$ svn import foodir
but that Arch and Perforce do not have recursive imports so you have to
do something like (again, I'm guessing here):
$ arch import foodir/file1 foodir/file2 foodir/dir1 ...
So if Brandon used some mechanism (UNIX find, perhaps) to generate all
the filenames in the Mozilla tree and pass them to arch via ARGV, that
he exceeded the limit of ARGC--a limitation of his shell.
Brandon, is that correct?
Anyway, I don't see the need for you to get all defensive here...
nobody's picking on arch.
