I've been hearing about The GNU PDF Library since 2007. Since then I've been looking forward to see this tool in the wild, but four years have passed and it seems to me that this is a painfully long time. I'm aware of the complexities of the project, but as I recall the GNU Foundation have marked it as a top priority project. What is going on?
Is GNU PDF Library in active development?
development;pdf;gnu
There seems to be some activity on http://lists.gnu.org/archive/html/pdf-devel/. Also, see http://gnupdf.org/manuals/gnupdf-hg-manual/html_node/Information-for-Newcomers.html#Information-for-Newcomers for information about cloning their repository. Specifically do $ bzr branch bzr://bzr.savannah.gnu.org/pdf/libgnupdf/trunk libgnupdfBazaar is a distributed version control system, and its command line client is called bzr.Looking at the repository is a good way to determine activity. You can see the logs by changing directory into the repository libgnupdf and doing bzr log -v | less. My two cents are that 929 revisions in slightly less than 4 years isn't so bad. Such projects usually have a shortage of manpower and of course everyone is a volunteer. If you have any specific questions, I'm sure the developers would be happy to answer, as long as you ask nicely.
