UICILIBRIS(1)						      uicilibris User Manual						     UICILIBRIS(1)

NAME

       uicilibris - a harvester for mediawiki contents, with LaTeX export

SYNOPSIS

       uicilibris

       uicilibris [--url=URL]

DESCRIPTION

       uicilibris is a harvester able to fetch contents from a mediawiki, assemble them consistently, exprt them to LaTeX format, compile the
       source, and deal interactively with errors.

OPTIONS

       --url=URL
	   Optionnally loads the given URL (which must be in a mediawiki).

       When uicilibris is invoked without arguments, it enters GUI mode and accepts URLs to be dragged and dropped in its first panel tab.

KNOWN BUGS

       This package does not imprment a grammatical parser for mediawiki code. So it can be fooled by some particular inputs. Beware of the
       following: underscores in image file names should be avoided (replace them by hyphens), avoit using successive curly braces in mathemeatic
       formulas when these are inside mediawiki templates. Just separate consecutive braces by spaces, which does not harm for LaTeX mathematic
       formulas.
