bgneal@591 1 """make_fixed_page.py
bgneal@584 2
bgneal@591 3 A management command to generate HTML files that can be {% include'd %} by a
bgneal@591 4 generic flatpage-like system. We currently support restructured text as input.
bgneal@591 5
bgneal@591 6 I chose "fixed" page since I didn't want to confuse this with Django's flatpage
bgneal@591 7 system.
bgneal@591 8
bgneal@591 9 This command reads input files from the directory PROJECT_PATH/fixed and writes
bgneal@591 10 the HTML output to PROJECT_PATH/templates/fixed.
