### design choices
#### keeping the parser and the access control separate
There are two programs concerned with access control:
* `gl-auth-command`, the program that is run via `~/.ssh/authorized_keys`;
this decides whether git should even be allowed to run (basic R/W/no
access). (This one cannot decide on the branch-level access; it is not
known at this point what branch is being accessed)
* the update-hook on each repo, which decides the per-branch permissions
I have chosen to keep the relatively complex task of parsing the config file
out of them to keep them simpler (and faster). So any changes to the config
have to be first "compiled", and the access control programs use this
"compiled" version of the config. (The compile step also refreshes
`~/.ssh/authorized_keys`).
If you choose the "easy install" method, all this is quite transparent to you
anyway. If you cannot use the easy install and must install manually, I have
clear instructions on how to set it up.
#### why we don't do "excludes"
[umm... having said all this, I implemented it anyway; see the "rebel"
