# 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. As well as testing that they work,
# we use --disable-shared or --disable-static after the first test (which
# builds both) to save a bit of time by building only one version for the
# subsequent tests.

# 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.

# This is in case the caller has set aliases (as I do - PH)
