QSource-Highlight uses the library included in GNU Source-Highlight,
since version 3, thus you need that library to build QSource-Highlight;
in particular it uses Source-Highlight-Qt additional library,
http://srchiliteqt.sourceforge.net, which provides highlighting in Qt
relying on GNU Source-Highlight. Thus, you need to install
Source-Highlight-Qt as well. we refer to GNU Source-Highlight's and
Source-Highlight-Qt's websites for further information about the library
and its installation (you may want to check whether your distribution
already provides packages for these two libraries).
You can highlight your code on the fly, and have the highlighted output
in all the formats supported by source-highlight (e.g., HTML, LaTeX,
Texinfo, etc.). You can then copy the formatted output and paste it
(e.g., in your blog), or save it to a file.
A preview of the highlighted output is available for some output formats
(e.g., HTML, XHTML, etc.).
