<!--
grammar regeneration logic
we do this with ant for several reasons:
* remove generated tabs for forbidden-apis
* remove generated timestamps/filenames for reproducible build
* fix CRLF line endings for windows consistency
* ability to make classes package-private
* keeping in source code control is easier on IDEs
2017-01-19 11:41:50 -05:00
* regeneration should be rare, no reason to be religious about generated files
* all logic already written and battle tested in lucene build
