"""
|
|
Provides basic functionality for handling RSS/RDF feeds. Depends on the Alias
|
|
module for user-friendliness: instead of:
|
|
|
|
rsstitles http://slashdot.org/slashdot.rss
|
|
|
|
It'll make the alias:
|
|
|
|
alias slashdot rsstitles http://slashdot.org/slashdot.rss
|
|
|
|
And you'll be able to call the command like this:
|
|
|
|
slashdot
|
|
|
|
Commands include:
|
|
rsstitles
