   3 # "assemble-all-pages" inserts the constant parts into all HTML templates
   4 # in the working directory and creates the OS-specific pages by removing
   5 # the irrelevant text from a common file which contains the OS-variable
   6 # parts.
   7
   8 # The page is NAME.html and the template is NAME.t.html. The template has
   9 # inclusion markers (similar to SSI directives, except for the lack of "#")
  10 # to indicate where the constant parts are to be inserted, and deletion
  11 # markers to identify the borders of each deletion and indicate which
  12 # page(s) the text between them belongs to.

  16 # Script:     assemble-all-pages

  19 #             index.t.html  (contains variable parts for mac and windows)
  20 #             infographic.t.html
  21 #             next_steps.t.html

  29 # To regenerate the pages in [...]/enc/[lang]/:
  30 # - In the terminal, cd to [...]/enc/[lang]/kitchen/ and enter:
  31 #                     $ ./assemble-all-pages
  32 # - Or, in the file browser, display the directory [...]/kitchen/ (not its
  33 #   parent) and double-click on the script.

  35 # And if anything goes wrong, you can do a git reset, right?    ;-)
