-# This script handles all the mechanical steps of importing irregexp from v8:
-#
-# 1. Acquire the source: either from github, or optionally from a local copy of v8.
-# 2. Copy the contents of v8/src/regexp into js/src/regexp
-#    - Exclude files that we have chosen not to import.
-# 3. While doing so, update #includes:
-#    - Change "src/regexp/*" to "regexp/*".
-#    - Remove other v8-specific headers completely.
-# 4. Add '#include "regexp/regexp-shim.h" in the necessary places.
-# 5. Update the VERSION file to include the correct git hash.
-#
-# Usage:
-#  cd path/to/js/src/regexp
-#  ./import-irregexp.py --path path/to/v8/src/regexp
-#
-# Alternatively, without the --path argument, import-irregexp.py will
-# clone v8 from github into a temporary directory.
-#
-# After running this script, changes to the shim code may be necessary
-# to account for changes in upstream irregexp.
