#   go.sh [systems]
#
# Convenience script to generate systems.  Do not call from build steps or tests
# - call fremontcutbuilder and dartdomgenerator instead. Do not add 'real'
# functionality here - change the python code instead.
#
# I find it essential to generate all the systems so I know if I am breaking
# other systems.  My habit is to run:
#
#   ./go.sh | tee Q
#
# I can inspect file Q if needed.
#
# To generate a subset of systems:
#
#   ./go.sh dart2js,htmldartium
#
# To re-gen all sdk/lib files (outside of a Dartium enlistment the file
# 'sdk/lib/js/cached_patches.dart' might not need to be generated).  To run
# go.sh w/o the patches files used --no-cached-patches switch e.g.,
#
#  ./go.sh --no-cached-patches
#
# The following gives a picture of the changes due to 'work'
#
#   git checkout master               # select client without changes
#   ./go.sh
#   mv ../generated ../generated0     # save generated files
#   git checkout work                 # select client with changes
#   ./go.sh
#   meld ../generated0 ../generated   # compare directories with too
