When you clone the Git repository of those grammar libraries (which
AFAIK is the only way to get their sources), you get all the source
files, including the Javascript sources of the grammar, the corpus of
text that they used, the test files, etc.  You also get the C/C++
sources of the parser and the scanner (produced from the grammar
files), which you then need to compile and link into a library.

So in the above you are barking up the wrong tree, and you should know
me better than lecture me on software freedom and what it means.
