# shlib-wrapper - execute shlib utilities from dev environments
#
# This wrapper allows the execution of shlib based applications from within the
# source-code environment. I.e. the application is not installed
#
# The wrapper requires that the following exist as a minimum.
# <project>/shlib.config
# <project>/<command> -> libexec/shlib/shlib-wrapper
# <project>/libexec/<project>/<command>
# <project>/libexec/shlib/shlib
