Dear sage-support
I made a html version of Sage quick refcards at
http://user.mendelu.cz/marik/sage/quick/quick.html for my students.
You may find it interesting also for you or your students.
Some cleaning is still necessary and will be done perhaps within few
days, but it is usable right now.
If you want to customize this page for you (number theory and graph
theory is commented out), download *.tex, *.png, tes4ht.usr, marik-
jsmath.4ht from http://user.mendelu.cz/marik/sage/quick/ and compile
by the following command
htlatex quick "xhtml,jsmath,marikjsmath" " -cmozhtf"
Thanks to all authors of PDF refcards for making the sources of
refcards available
Robert Marik
