This module provides a simple method of testing that a MANIFEST matches the distribution. It tests three things: Everything in MANIFEST exists Everything in the package is listed in MANIFEST, or subsequently matches a regular expression mask in MANIFEST.SKIP Nothing exists in MANIFEST that also matches a mask in MANIFEST.SKIP, so as to avoid an unsatisfiable dependency conditions If there is no MANIFEST.SKIP included in your distribution, this module will replicate the toolchain behaviour of using the default system-wide MANIFEST.SKIP file. To view the contents of this file, use the command: $ perldoc -m ExtUtils::MANIFEST.SKIP
