+# The Sieve interpreter can retrieve Sieve scripts from several types of
+# locations. The default `file' location type is a local filesystem path
+# pointing to a Sieve script file or a directory containing multiple Sieve
+# script files. More complex setups can use other location types such as
+# `ldap' or `dict' to fetch Sieve scripts from remote databases.
+#
+# All settings that specify the location of one ore more Sieve scripts accept
+# the following syntax:
+#
+# location = [<type>:]path[;<option>[=<value>][;...]]
+#
+# If the type prefix is omitted, the script location type is 'file' and the 
+# location is interpreted as a local filesystem path pointing to a Sieve script
+# file or directory. Refer to Pigeonhole wiki or INSTALL file for more
+# information.

+  # delivery. The "include" extension uses this location for retrieving
+  # :personal" scripts. This is also where the  ManageSieve service will store
+  # the user's scripts, if supported.
+  # 
+  # Currently only the 'file:' location type supports ManageSieve operation.
+  # Other location types like 'dict:' and 'ldap:' can currently only
+  # be used as a read-only script source ().
