This utility can be used to verify the version of an installedpackage against version constraints. The version constraints canbe specified in typical cabal fashion (e.g. >= 8.3, == 0.9.*, >= 8.3 && < 9.0).

Usage: cabalvchk package-name version-constraints [verbose]

Note that the version-constraints will probably need to be enclosed insingle-quotes to prevent the shell from interpreting characters in thespecification.

One use of this utility is by external configuration/validation utilities(e.g. autoconf) to verify installed package versions without running acabal build. This utility produces no output (unless a third argument isspecified) and the return value is 0 if the constraints are met or non-zeroif the constraints are not met (including if the package is not installed).

Changes in 0.3:

• Changed category to Distribution

• Only consider exposed packages

Changes in 0.2:

• Handles multiple package installations by returning 0 if any of theinstalled versions satisfies the constraints.
