Drupal 7

i hadn't seen this module when i was looking to do this in D7 so i did it somewhat different.. i created a new .inc that would need to be loaded from vbo.module by also adding 1 line to include that inc as the others are included (technically vbo should just auto load all the .inc files and then it wouldn't need to be modified)

not sure what the D6 module's UI is but this adds a configurable action which can select which style (d6 icache preset) to use in the action; so user can create as many actions as required for whichever styles are required (incl original). so you can end up with something like this: http://screencast.com/t/wV9dWOY1i9t

would be pretty simple to convert this to a stand alone module

issues:
- token support is limited in what i can see (same as std file archive inclu with vbo) in that i do not see a way to use node related tokens since batch api loses args and vbo doesn't seem to pass nid or node object.
- also, i think the way the std vbo file archive does zip create is wrong; they create a zip and then open, add, close to that file each time next file is processed. i think this prevents using any sort of time based tokens as the zip file name which change when time is different. it also seems far less efficient than simply collecting up all the files; and then adding all at once to zip which is how i am doing it.

ughh.. and the .inc

NOTE: you must also add 1 line to vbo.module to include this file - there is a function where all the other action .incs are included)

this version is better..
