# When adding a new standard build system module, these are the places where
# you will need to make changes (igrep for the name of one of the existing
# modules to locate all the places):
#
# - this buildfile
# - build/bootstrap.build (submodules; should be handled automatically)
# - build scripts: build.sh.in and build-*.bat.in
# - documentation: BOOTSTRAP-*.cli and UPGRADE.cli (multiple places)
# - install scripts: prepare, build2-install.sh, and build2-install-*.bat
# - build2.org/www/ (module docs symlinks for both public and stage, etc)
# - make sure the module has `builds: all` in its manifest
# - make sure just `b noop: libbuild2-<mod>-tests/` works and loads the module
#   (not that noop does not do implicit directory buildfile loading)
# - make sure the module is listed in the mod array in etc/bootstrap
