Subject: - add option to build in a different base than $PWD (nightly builds now
X-Git-Tag: planetlab-2_0-branch-point~2
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=34921b4a82c6c138b56168315bdfaf97b501bbd9;p=build.git

- add option to build in a different base than $PWD (nightly builds now
  go in $HOME/build/nightly/, see crontab). Tagged builds should go in
  $HOME/build/.
- add option to mail results (with mail(1)), rather than depending on
  cron to do it, which uses a nasty unreadable subject line
- add option to clean base of old runs
- add -h help option
- simply stdout/stderr redirection to log file
