Here are some OpenACS packages I have written:

QA tools v 0.1d
QA tools which check .info, .xql, docbook, and procedure documentation.
CVS Log analyzer 0.1d
parses a log file and displays change sets and some statistics. Links into cvsweb for diffs. See it here. Currently has a lot of OpenACS specific stuff hard coded but could be generalized fairly easily

The version of photo-album running here is now checked in to the regular package section at openacs.org. In case you need the old tarball for some reason here it is:

I am running rl_returnz which gzip encodes the returned data to improve download times on slow connections. I have modified the original version to support setting the proper output encoding (which only works on aolserver 3.3+ad13 since it uses NsConnEncodeForOutput and other of Rob Mayoffs i18n code). It's running here and seems to be ok but as with everything there are no guarantees. To use it I load the module and add these lines to my tcl/zz-postload.tcl file: 

rename ns_return ns_return_safe
rename rl_returnz ns_return

I generated a single file PDF for the aolserver core docs. Note that it is in pretty rough form but is useful if you need to get an idea of how much documentation exists (or if you want to print it and kill a tree). I generated it with FOP.
