+# what/why: re-establish gitolite admin access when admin key(s) lost
+# where:    on server (NOT client!)
+
+# pre-req:  shell access to the server (even with password is fine)
+# pre-work:  -  make yourself a new keypair on your workstation
+#            -  copy the pubkey and this script to the server
+
+# usage:    $0 admin_name client_host_shortname pubkeyfile
+# notes:     -  admin_name should already have RW or RW+ access to the
+#               gitolite-admin repo
+#            -  client_host_shortname is any simple word; see example below
+
+# WARNING: ABSOLUTELY NO ARGUMENT CHECKING DONE
+# WARNING: NEWER GITS ONLY ON SERVER SIDE (for now)
+
+# example:  $0 sitaram laptop /tmp/sitaram.pub
+# result:   a new keyfile named sitaram@laptop.pub would be added
