looking for xml files. Added service definition files for two sample
|

services. It only supports passing the selection to the service;
|
||||
passing the entire document is coming soon.
|
||||
|
||||
* components/text/Makefile.am:
|
||||
include the services directory in the build
|
||||
|
||||
* configure.in:
|
||||
* components/text/services/.cvsignore:
|
||||
* components/text/services/Makefile.am:
|

build stuff for services directory
|

* components/text/services/google.xml:
|

* components/text/services/webster.xml:
|
||||
definition files for our twp sample services
|

|
||||
* components/text/nautilus-text-view-ui.xml:
|

removed hardwired service menu items
