Re: [Transmogrify-development] java grammer 1.3 (printing comments)

[Matt B. <gud...@ya...>]

I haven't worked on the Jext port of Transmogrify in
quite some time; I first had to put together a working
prototype of Jext's Project API which is being built
for the purpose of better integrating Transmogrify (we
hope to use its analytics for all Java parsing tasks).
 I am about ready to resume work on the port but had
not heard that comments had been fixed, so assumed
otherwise.  Again those were a must so I am glad to
hear that they are no longer a problem.  I will advise
the list of any difficulties I encounter whenever I
get back to working on this (hence my comment about
having a life being a problem for open-source
developers :)  ).
