## Description target [ : description ]
|
|
## Provides access to the description of 'target'. The description may be
|
|
## used by other rules, such as those which generate project files, or which
|
|
## present informative messages to the user regarding 'target'. If invoked
|
|
## with two arguments, then it sets the description of 'target'. If invoked
|
|
## with one argument, then it returns the description of 'target'. You
|
|
## should invoke this rule to set the description before invoking other
|
|
## rules which might need access to target's description, such as the
|
|
## Application, Library, and Plugin rules. As a convenience, several generic
|
|
## rules, such as Application, Library, and Plugin will automatically invoke
|
|
## the Help rule for 'target' using the provided 'description'.
