#  What is This Script?
###########################

# testcurl.pl is the master script to use for automatic testing of CVS-curl.
# This is written for the purpose of being run from a crontab job or similar
# at a regular interval. The output is suitable to be mailed to
# curl-autocompile@haxx.se to be dealt with automatically (make sure the
# subject includes the word "autobuild" as the mail gets silently discarded
# otherwise).  The most current build status (with a resonable backlog) will
# be published on the curl site, at http://curl.haxx.se/auto/

# USAGE:
# testcurl.pl [options] [curl-daily-name] > output

# Options:
#
# --configure=[options]    Configure options
# --crosscompile           This is a crosscompile
# --desc=[desc]            Description of your test system
# --email=[email]          Set email address to report as
# --extvercmd=[command]    Command to use for displaying version with cross compiles.
# --mktarball=[command]    Command to run after completed test
# --name=[name]            Set name to report as
# --nocvsup                Don't update from CVS even though it is a CVS tree
# --nobuildconf            Don't run buildconf
# --runtestopts=[options]  Options to pass to runtests.pl
# --setup=[file name]      File name to read setup from (deprecated)
# --target=[your os]       Specify your target environment.
#
# if [curl-daily-name] is omitted, a 'curl' CVS directory is assumed.
#
