Subject: [PATCH] Bug 34817: Framework plugin callnumber_colors
Content-Type: text/plain; charset=utf-8

Test plan:
Add this to your IntranetUserCSS:
  .callnumber_green { background-color: green; } /* callnumber_colors.pl framework plugin */
  .callnumber_red { background-color: red; } /* callnumber_colors.pl framework plugin */
Goto Administration/MARC bib framework. Add callnumber_colors.pl as plugin to 952$o.
Goto Cataloguing/Edit items.
Test the plugin with a new and existing item. Test response on existing
callnumber, not existing, clearing field.
