Compatibility alert: staticdirindex is built on and is dependent on

staticdir and its configurations. staticdirindex only works effectively

in locations where staticdir is also configured. staticdirindex is

coded to allow easy integration with staticdir, if demand warrants.

|
indexlister must be configured, or no function is performed.

indexlister should be a callable that accepts the following parameters:
|
|
section: same as for staticdir (and implicitly calculated for it)
|
|
dir: same as for staticdir, but already combined with root
|
|
path: combination of section and dir
|
|
|
|
Other parameters that are configured for staticdirindex will be passed
|
|
on to indexlister.

served by staticdir, call staticdirindex.
