The cabalvchk package
This utility can be used to verify the version of an installed package against version constraints. The version constraints can be 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 in single-quotes to prevent the shell from interpreting characters in the specification.
One use of this utility is by external configuration/validation utilities (e.g. autoconf) to verify installed package versions without running a cabal build. This utility produces no output (unless a third argument is specified) and the return value is 0 if the constraints are met or non-zero if the constraints are not met (including if the package is not installed).
