test_description='gitweb as standalone script (http status tests).

This test runs gitweb (git web interface) as a CGI script from the
commandline, and checks that it returns the expected HTTP status
code and message.'

# Gitweb only provides the functionality tested by the 'modification times'
# tests if it can access a date parser from one of these modules:

perl -MHTTP::Date -e 0 >/dev/null 2>&1 && test_set_prereq DATE_PARSER
perl -MTime::ParseDate -e 0 >/dev/null 2>&1 && test_set_prereq DATE_PARSER
