+# cfilter.vim: Plugin to filter entries from a quickfix/location list
+# Last Change: Jun 30, 2022
+# Maintainer: Yegappan Lakshmanan (yegappan AT yahoo DOT com)
+# Version: 2.0
+#
+# Commands to filter the quickfix list:
+#   :Cfilter[!] /{pat}/
+#       Create a new quickfix list from entries matching {pat} in the current
+#       quickfix list. Both the file name and the text of the entries are
+#       matched against {pat}. If ! is supplied, then entries not matching
+#       {pat} are used. The pattern can be optionally enclosed using one of
+#       the following characters: ', ", /. If the pattern is empty, then the
+#       last used search pattern is used.
+#   :Lfilter[!] /{pat}/
+#       Same as :Cfilter but operates on the current location list.
+#
