# Fancy Index module Hacking HOW-TO ## How to modify the template The template is in the `template.html` file. Note that comment markers are used to control how the `template.awk` Awk script generates the C header which gets ultimately included in the compiled object code. Comment markers have the `` format. Here `identifier` must be a valid C identifier. All the text following the marker until the next marker will be flattened into a C string. If the identifier is `NONE` (capitalized) the text from that marker up to the next marker will be discarded. ## Regenerating the C header You will need Awk. I hope any decent implementation will do, but the GNU one is known to work flawlessly. Just do: $ awk -f template.awk template.html > template.h If your copy of `awk` is not the GNU implementation, you will need to install it and use `gawk` instead in the command line above.
