Roadmap:

  Makefile -- nothing interesting.

  PLD_Builder/ -- all python stuff live here.

  admin/ -- scripts for chroot admin.

  architektura.txt -- docs, in Polish.

  client/ -- scripts for clients, i.e. developers sending requests

  config/ -- configuration

  go.py -- testing script, don't touch

  bin/ -- scripts for builder account outside chroot
  
    request-handler.sh
      Script to be run from procmail on src builder. It process incoming
      request, authorizes it and stores in spool/queue.

    src-builder.sh
      Script to be run from cron on src builder. It looks for new
      requests in spool/queue, gets them from there, builds SRPM, and
      stores request for binary builders in spool/req_queue (which is
      mirrored in www/ directory, signed and compressed). SRPMS and
      buildlogs are queued for transmission.

    request-fetcher.sh
      Run on binary builder.
      Fetch queue.gz from src-builder, and distribute requests for all
      builders hosted on given account (to spool/queue-<builder> files).

    rpm-builder.sh <builder>
      Run on binary builder.
      Tries to aquire locks for <builder> and for job-slot. If that suceeds, 
      proccess one request from spool/queue-<builder>.

    load-balancer.sh
      Run on binary builder.
      Checks spool/got_lock. Then run rpm-builder.sh in order determined
      from this file (if b1 had lock last time before b2, first run
      rpm-builder.sh b1 and then rpm-builder.sh b2), so builders get
      the same number of requests.

    file-sender.sh
      Run on both binary and src builder.
      Sends files queued in spool/{ftp,buildlogs}.
  
Working directories:
  lock/
  spool/
  log/
