# There are two parts to this script:
# 1) Generate tutorial main page sections by substituting code sections into
#    the html templates under $COGL_SRC/tutorials
# 2) Generate final web pages by substituting page sections into a
#    template.html file according to a set of "mustache" markers.
#
#    This script greps for all the "mustache" markers in template.html like
#    {{foo}} and {{bar}} and then for each sub directory (PAGE) under pages/ we
#    make a www/PAGE.html by copying template.html and substituting any
#    pages/DIR/MUSTACHE_MARKER_NAME.html files we find that matches the names
#    we found in the template. Markers without a corresponding file are simply
#    stripped.
