  3## Script to build and test the latest python from svn.  It basically
  4## does this:
  5##   svn up ; ./configure ; make ; make test ; make install ; cd Doc ; make
  6##
  7## Logs are kept and rsync'ed to the host.  If there are test failure(s),
  8## information about the failure(s) is mailed.
  9##
 10## This script is run on the PSF's machine as user neal via crontab.
 11##
 12## Yes, this script would probably be easier in python, but then
 13## there's a bootstrap problem.  What if Python doesn't build?
 14##
 15## This script should be fairly clean Bourne shell, ie not too many
 16## bash-isms.  We should try to keep it portable to other Unixes.
 17## Even though it will probably only run on Linux.  I'm sure there are
 18## several GNU-isms currently (date +%s and readlink).
 19##
 20## Perhaps this script should be broken up into 2 (or more) components.
 21## Building doc is orthogonal to the rest of the python build/test.
 22##
 23
 24## FIXME: we should detect test hangs (eg, if they take more than 45 minutes)
 25
 26## FIXME: we should run valgrind
 27## FIXME: we should run code coverage
 28
 29## Utilities invoked in this script include:
 30##    basename, date, dirname, expr, grep, readlink, uname
 31##    cksum, make, mutt, rsync, svn
 32
 33## remember where did we started from
