RFC: gnupg package?

Hello all, I am planning to develop an php-to-gnupg interface class and to make it available via PEAR, as the PECL gnupg extension has some really annoying bugs and is unusable for me. Currently the basics of gnupg are implemented (sign, verify and crypt). The code is available on < http://velirat.de/websvn/listing.php?repname=gnupg&path=%2F&sc=0>. Anything that I can improve - documentation, code or the way the code is designed? Thanks, Marco Schuster PS: yes, I know that decrypt is missing, it will be in the repo in 24hrs.
