# This script simplifies the preparation of the environment for a Subversion client
# communicating with an svnserve server.
#
# The script runs svnserve, runs "make check", and kills the svnserve afterwards.
# It makes sure to kill the svnserve even if the test run dies.
#
# This script should be run from the top level of the Subversion
# distribution; it's easiest to just run it as "make
# svnserveautocheck".  Like "make check", you can specify further options
# like "make svnserveautocheck FS_TYPE=bdb TESTS=subversion/tests/cmdline/basic.py".
