  35 # This directory provides a unified place for building all kinds of
  36 # GROMACS documentation. This includes some "static" content (Doxygen
  37 # code documentation, reference manual, install guide, old online HTML
  38 # images), and content generated from the gmx program for the various
  39 # tools (man and HTML pages). It also provides the "webpage" target,
  40 # that combines all of the above (except man pages in man format) into
  41 # a form suitable for automated deployment to the GROMACS website. It
  42 # also provides the INSTALL file for the tarball.
  43 #
  44 # The webpage is mostly built by Sphinx.  Variable values for Sphinx
  45 # substitutions are configured by CMake (for things like version numbers),
  46 # using gmx_configure_version_file().  This happens during build time instead
  47 # of configure time, because 1) some of the version variables are only
  48 # available during build time, and 2) we don't want to do all the Sphinx setup
  49 # during configuration to save some time when not building the content.
  50 # All the generated values get put into conf-vars.py (generated from
  51 # conf-vars.py.cmakein), which in turn is included by the Sphinx configuration
