   6 ## Synopsis:             assemble-all-pages

   8 ## Description
   9
  10 # Each page is built from a template and one or several includes, as usual;
  11 # in addition, several versions of a page can be built from a single
  12 # template which contains all the variable parts, by deleting irrelevant
  13 # text.
  14
  15 # The templates have inclusion markers (similar to SSI directives, except
  16 # for the lack of "#") to indicate where the constant parts are to be
  17 # inserted, and deletion markers to identify the borders of each deletion
  18 # and indicate which page(s) the text between those borders belongs to.
  19
  20 # The script processes all the templates in the working directory and the
  21 # pages are created in the parent directory.
  22
  23 # Ideally, any modifications should be done to the templates or includes,
  24 # not to the final pages.
  25
  26 # Templates:  confirmation.t.html
  27 #             index.t.html  (contains variable parts for mac and windows)
  28 #             infographic.t.html
  29 #             next_steps.t.html
  30 #             workshops.t.html
  31
  32 # Includes:   footer.html
  33 #             head.html
  34 #             javascript.html
  35 #             translist.html

  37 ## Graphic-user-interface howto
  38
  39 # - Place the script in the same directory as the templates.
  40 # - Display this directory in the file browser (do not just unfold the parent
  41 #   directory) and double-click on the script.
  42
  43 # And if anything goes wrong, you can do a git reset, right?    ;-)
