# Determine readline patchlevel:
# Let's hope that in x86 we don't have >1 patch directory.  We're using wild cards here because
# Sud takes the version from the x86 file name, which happens in this package to include the
# patch level.  There aren't many packages like this, and even less that do things like
# adjust the patch level, so we'll just hack around it rather than make Sud cater for it.
