# documentation for this program is right here, please read
# IMPORTANT: also see usage notes below
# BACKGROUND/PURPOSE:
# - an external program populates "keydir" with *all* keys and then
# calls this program, giving "keydir" as arg-1
# - we then call gitolite.pm's "setup_authkeys" function to do its thing
# arg-1: keydir
# DISCUSSION:
#
# For now, we will assume *all* the keys are in the keydir passed. The
# setup_authkeys routine factored out from the old gl-compile-conf is not
# setup to take a partial set of keys and create the ~/.ssh/authorized_keys
# file.
#
# Also, there are issues to do with *deleted* keys that need to be taken care
# of.
#
# All in all, unless it is shown to be quite inefficient, I'd much prefer
# processing *all* keys each time there is a change.

This is a cronnable, batchable, program to rewrite ~/.ssh/authorized_keys
using public keys in a given directory. It MUST be run by supplying its
full path, and the rest of the gitolite scripts must be in the same
directory. Here's how to run it:
/full/path/to/gl-setup-authkeys -batch keydir
where 'keydir' contains a bunch of '*.pub' files.
If you're not sure what the full path to the script should be, look in
~/.ssh/authorized_keys for the path to the gl-auth-command script.
If you managed to lose that file (how careless of you!) then, depending on
what install mode you used, it's either \$HOME/.gitolite/src or \$HOME/bin
or /usr/local/bin or whatever your package maintainer decided. I leave it
to you to figure out which method gets you which PATH ;-) In this case
you'll also have to set GL_BINDIR to that same path *and* export it, so
something like this should do:
export GL_BINDIR=/that/full/path/you/just/found
\$GL_BINDIR/gl-setup-authkeys -batch keydir
The keydir can be found from the value of \$GL_KEYDIR in ~/.gitolite.rc\n\n";
