+# Notes         :
+# Preconditions:
+# - Packages doxygen doxygen-doc doxygen-latex doxygen-gui graphviz
+#   must be installed.
+# - Doxygen configuration file must have the destination directory empty and
+#   source code directory.
+# - A gh-pages branch should already exist.
+#
+# Required global variables:
+# - DOXYFILE            : The Doxygen configuration file.
+# - GH_REPO_NAME        : The name of the repository.
+# - GH_REPO_REF         : The GitHub reference to the repository.
+# - GH_REPO_TOKEN       : The GitHub application token.
+#
+# This script will generate Doxygen documentation and push the documentation to
+# the gh-pages branch of a repository specified by GH_REPO_REF.
+# Before this script is used there should already be a gh-pages branch in the
+# repository.
