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
Documentation
usageInfo :: String -> [DarcsOptDescr a] -> String
Variant of usageInfo
