# Note that this is the same variable as what's used by the import machinery
# when we import cli%exe{cli}. Here, however, we require it to be explicitly
# specified (i.e., no default search in PATH) in order for the regeneration
# to be enabled.
#
# Normally, in the development build, this variable will be set only in the
# cli package configuration to point to its own binary (or a binary in another
# build configuration if you want to play it safe).

# Load the cli module only if explicitly requested. This way a distribution
# that includes pre-generated files can be built without installing cli. This

# file prerequisites instead of using the cli.cxx{} group (it won't be there
# unless the module is configured).

#    via an ad hoc recipe.
