# This is a script for the use of PCRE maintainers. It configures and rebuilds
# PCRE with a variety of configuration options, and in each case runs the tests
# to ensure that all goes well. Every possible combination would take far too
# long, so we use a representative sample. This script should be run in the
# PCRE source directory.

# Some of the tests have to be skipped when PCRE is built with non-Unix newline
# recognition. I am planning to reduce this as much as possible in due course.
