# This is the script that generates the copy of the QmlJS parser from the sources
# in the qtdeclarative source tree.
#
# It applies a bunch of renames to make the source compatible with the Qt Creator
# sources as well as rewrites of the licenses.
#
# Example:
# cd src/libs/qmljs/parser
# QTDIR=~/path/to/qtdeclarative-checkout ./gen-parser.sh
