3 | ## assemble-all-pages -- generate a set of HTML pages with variable parts | |
4 | # for emailselfdefense.fsf.org | |
5 | ||
6 | ## Synopsis: assemble-all-pages | |
7 | ||
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 | |
8d0e67b7 | 30 | # workshops.t.html |

32 | # Includes: footer.html | |
de21d188 | 33 | # head.html |

34 | # javascript.html |
35 | # translist.html | |

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? ;-) | |
