[kepler-dev] Some quick questions

[Matthew Jones]

Colin --

To map an icon you need to add it to one of the icon mapping property 
files, either by LSID or classname or both:
    uiSVGIconMappingsByClass.properties
    uiSVGIconMappingsByLSID.properties

These are in configs/ptolemy/configs/kepler

In general you should choose one of the existing icons, which are 
categorized by functional groupings.  The older _iconDescription 
approach from Ptolemy is not used in Kepler.

There is no unified properties file for Kepler, but several others exist 
in that directory that might be of use to you for setting system level 
options -- we've used config.xml for most system level properties.

As far as your startup problem -- I'm not sure, but I suggest you clear 
your karlib by doing an ant full-clean before a full rebuild (including 
ant buildkarlib). Did you add an actor to the mix, and if so, have you 
tried a clean build without it to be sure its not something you added?

G'luck,

Matt
