description         TeX previewer for Mac OS X
long_description \
    TeXworks is a TeX previewer for Mac OS X, Linux, and Windows. \
    It uses the Qt4 GUI framework and the Poppler PDF rendering library \
    (compiled with Qt4 wrapper). \
    The TeXworks project has been founded by Jonathan Kew (scripts.sil.org/XeTeX), \
    the developer of XeTeX. It is inspired by TeXShop, the only TeX previewer \
    with a relative simple user interface. \
    Jonathan Kew: \"TeXworks aims to provide a simple TeX environment \
    based on modern standards (including Unicode encoding and PDF output by default) \
    with an uncluttered interface that does not overwhelm the newcomer. \
    It is built using cross-platform, open-source tools and libraries, \
    so as to be available on all today's major operating systems, \
    with a native look and feel for each.\" \
