Turn 'foo.html.src' into 'foo.html', which will have autogenerated navigation and footer. make Update whatever is necessary. Input format ============ Macro preprocessor. --conf= ... Where filename SHOULD end with '.src', for automation using make, the filename MUST end with '.src'. And the footer file whose path/name is stored in the configuration file. 'foo.html' is generated from 'foo.html.src' and the footer can be included with a macro. Macros are expanded using Python's builtin str.replace(src, dest) '__X__H1__FOO__' becomes '__X

...

FOO__'. Looks undefined != is undefined. __H1__

Name for the page, from the navigation tree.

__TITLE__ Same as __H1__ __TIMESTAMP__ Time when output was generated. __MODIFIED__ Time of last modification of the source file. __LINK_ARG__ URL-escaped absolute URL for this page, http://validator.w3.org/check?uri=__LINK_ARG__ __OUT_T__ 'output' if OUTPUT file does not have execute permission, 'script' if output file has execute permission. 'output generated ' would be misleading if it `said` by a CGI script that generates FRESH content. __URI__ Server-relative URI, eg. /foo.html __FOOTER__ This is the ONLY macro that cannot be used in the footer-file. Configuration file ================== --conf= [args...] The configuration file contains a Python datastructure, it is read using Python's own parser.

The root of the webserver is '/'. `name` is the default title and h1 fo the page. NOTE: You can set title and h1 manually, don't forget that. `children` is either None or a list [] of tuples () of (URL, name, children). 'subs' - Extra pages that don't fit in the navigation, they are always included in the navigation and they are always on the bottom. - ex. Privacy policy, Terms of use, etc. - List [] of tuples () of (URL, name). - Look at the documentation for 'tree', for information about `URL` and `name`. 'hidden' - Extra pages that shouldn't be shown in the navigation. - ex: Error pages - List [] of tuples () of (URL, name). - Look at the documentation for 'tree', for 'conf' Path to . string 'script' Path to . string 'footer' Path to the footer file. string 'host' Hostname, no protocol nor trailing slash. ex.
