+ list(SORT <list> [COMPARE <compare>] [CASE <case>] [ORDER <order>])
Sorts the list in-place alphabetically.
+Use the option ``<compare>`` to select the compare type for sorting.
+The ``<compare>`` option may be one of:
+
+* ``STRING``: Sorts a list of strings alphabetically.
+* ``FILE_BASENAME``: Sort a list of pathnames of files by their basenames.
+
+Use the option ``<case>`` to select a case sensitive or case insensitive sort mode.
+The ``<case>`` option may be one of:
+
+* ``SENSITIVE``: Sorts the list alphabetically.
+* ``INSENSITIVE``: Sorts the list alphabetically in descending order.
+
+Use the option ``<order>`` to select a case sensitive or case insensitive sort mode.
+The ``<order>`` option may be one of:
+
+* ``ASCENDING``: Sorts the list in ascending order.
+* ``DESCENDING``: Sorts the list in descending order.
