Crawler actions...

[Brian Foster <ho...@me.com>]

Hey guys... I've been slowly chuggin away at integrating cas-cli into cas-crawler... busy few weeks at work... but I'm also kinda stuck on something... currently the crawler supports command line options which configure crawler actions (not command line actions), however there is no way to display the help for these (i.e. whether they are required or not)... this is because they become required only if another option (i.e. -ais) is specified with their action id... new cas-cli doesn't support this either and I initially thought about adding this feature to cas-cli but didn't for simplicity sake (cas-cli is complex enough)... so I'm think of just make crawler action configurable via java properties... this will not change the currently implemented classes at all or the way actions are written in the future... basically spring will just set its properties for these actions by using java properties instead... what u guys thing?

I'd be +1 for this if the command line for the crawler worked the same way. Are you proposing
that CrawlerLauncher would now simply read command line actions and then have the 
Crawler's CommandLine actions set Spring java properties which would then be ready by the 
CrawlerActions?

Cheers,
Chris
