# Regenerate the options parsing code (included into the repository).
#
# 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).
#
# Note, though, that currently referring to the cli target in the project
# itself ends up with the 'dependency cycle detected' error. In the future we
# will fix that by using an ad hoc recipe instead of the cli module. But for
# now you can workaround this issue by pointing to a binary in another
# configuration.
