kompozer is available at http://kompozer.net/ as binary. but their are also 64 bit versions available at divers depositories for Ubuntu. and it would be possible to install blue-griffon, available in both, but considerably bigger in size (8 MB --> over 30 MB).
what is the best? can slitaz-rolling-core64 directly use 32 bit versions including for tools like dictionaries?
(independant from the version, the choice of dictionaries can be an important factor: kompozer uses myspell and offers adequate and slim old dictionaries on above site. blue-griffon will probably use the terrible big actual hunspell dictionaries and procede to a version control like seamonkey? why not directly seamonkey, is on the slitaz depository? different from lo, oo, calligra, seamonkey is big has no menu entries and desktop icons ready to use! seamonkey is bigger in size than kompozer (but not so big than blue-griffon). so is kompozer in my opinion better for a minimalist distro like slitaz)
