+\fBselector\fP is a command line utility for interactive real-time
+pattern matching. It reads the content of the specified files, and as
+the user types a list of strings separated by ";" (or a regexp), the
+display is updated in real time to show only the lines containing all
+the said strings (or matching the regexp).
+
+This command was mainly designed as a way to search efficiently in the
+shell history, for which it is substantially better than the standard
+readline ^R binding. With the -v option, it injects the selected line
+into the tty input buffer, hence allowing the user to edit the line
+and execute it as a standard command.
+
+Selector is also a handy tool to test regexps, or to display menus
+with many possible choices. For the latter, the -x option allows to
+show different strings than the ones returned.
+
+Note that because this is an interactive command, the standard input
+can not be used as one of the input files.
