Here are some useful binary files for fetching and converting content for the iLiad, run from the iLiad itself, possibly automatically using e.g. cron (if you use adamb's updated busybox).
Firstly there is "curl" for fetching URLs, which is more powerful than GNU wget (and much more useful than the version of wget installed on the iLiad). See e.g.
http://www.samhart.com/cgi-bin/class.../Wget_And_Curl for comparison.
Secondly there is "convert" from the imagemagick software, which can be used to convert and combine images into one pdf file. Note html2ps and whatever else is required to convert html to pdf isn't included here: like the comic fetching mentioned elsewhere I just wanted to automatically fetch images (and combine them into one pdf). When you run the convert binary the shell variable LD_LIBRARY_PATH needs to point to the directory where the libraries are.
