free/open documentation formats
for some future and current works i want to provide my writings
additionally in other formats than xhtml. Has anyone a link to a list
of free documentation formats? The problem is that i want to avoid
using formats on that evtl. patents are pending.
for example, i would like to provide my stuff using portable document
format (pdf) and postscript (ps), but i am not shure if the formats as
such are free cos adobe has a trademark on them.
thanks in advance,
p.s. i would be happy to get some hints on good viewers. should be
pure console/X/gtk viewers. e.g., is there a substitute for acrobat
reader that does also do well?
