A few months back, on the TODO list for LibreJS, it was suggested
that we create a patch for websites to ease the freeing of their
javascript. I've got the start of a bash script that would free
an entire directory tree of javascript. I'm not sure if that's
what the idea was, but for the moment, this will insert the
@licstart/@licend markers for the MPL and Apache licenses, or
insert the users choice of AGPL, MPL, or Apache licenses if no
license is found. I think this might help while we work out
other options.
