darcs-2.14.4: a distributed, interactive, smart revision control system

Darcs.UI.Usage

Description

This module provides a variant of usageInfo.

Unlike the standard usageInfo function, lists of long switches are broken across multiple lines to economise on columns. For example,

   -r  --recursive           add contents of subdirectories
--not-recursive,
--no-recursive        don't add contents of subdirectories

usageInfo :: String -> [DarcsOptDescr a] -> String Source #

Sequences of long switches are presented on separate lines.
