#!/usr/bin/perl -w

# shim program

# arg-1: keydir

# - an external program populates "keydir" with *all* keys and then
#   calls us, giving "keydir" as arg-1
# - we then call gitolite.pm's "setup_authkeys" function to do its thing

# IMPLEMENTATION NOTE: make sure this is in the same directory as
# "gitolite.pm" and all the rest of "src/".

# 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.

    If you are ABSOLUTELY sure you know what you're doing, here's how:

        $0 -batch keydir

    where 'keydir' contains a bunch of '*.pub' files\n\n";
    exit 1;
}

# quick sanity check and run
my $keydir = shift or die "I need a directory name\n";
-d $keydir or die "$keydir should be a directory\n";

&setup_authkeys($bindir, $keydir);
