+Usage:
+
+  Use this script to add a custom field to your Bugzilla installation
+  by invoking it with the --name and --desc command-line options:
+
+  $command --name=<field_name> --desc="<field description>"
+
+  <field_name> is the name of the custom field in the database.
+  The string "cf_" will be prepended to this name to distinguish
+  the field from standard fields.  This name must conform to the
+  naming rules for the database server you use.
+  
+  <field description> is a short string describing the field.  It will
+  be displayed to Bugzilla users in several parts of Bugzilla's UI,
+  for example as the label for the field on the "show bug" page.
+
+Warning:
+
+  Custom fields can make Bugzilla less usable.  See this URL
+  for alternatives to custom fields:
+  
+  http://www.gerv.net/hacking/custom-fields.html
+  
+  You should try to implement applicable alternatives before using
+  this script to add a custom field.
