The -H or --home-url
option allows you to specify a different description file than the
default one. For example, the command,
% Spider.py -H plucker:/test.html -f TestDB
tells the parser to build a database called TestDB.pdb using the
description file test.html that can be found in $PLUCKERDIR
(plucker: is relative to $PLUCKERDIR). You can also use
an absolute path,
% Spider.py -H file:/home/pilot/.plucker/test.html -f TestDB
would produce the same result as the first example.
Instead of using a local file we can use a file at a remote location,
% Spider.py -H http://plucker.gnu-designs.com/ -f PluckerDB
and the parser would use the index page for Plucker's home page as the
description file.
NOTE: The -H option needs a valid URL, so
don't use,
% Spider.py -H file:test.html -f TestDB
even if you are running the spider in the same directory as the file is located in.
