-"""SCons.Variables.PathVariable
-
-This file defines an option type for SCons implementing path settings.
-
-To be used whenever a a user-specified path override should be allowed.
-
-Arguments to PathVariable are:
- option-name = name of this option on the command line (e.g. "prefix")
- option-help = help string for option
- option-dflt = default value for this option
- validator = [optional] validator for option value. Predefined
- validators are:
-
- PathAccept -- accepts any path setting; no validation
- PathIsDir -- path must be an existing directory
- PathIsDirCreate -- path must be a dir; will create
- PathIsFile -- path must be a file
- PathExists -- path must exist (any type) [default]
-
- The validator is a function that is called and which
- should return True or False to indicate if the path
- is valid. The arguments to the validator function
- are: (key, val, env). The key is the name of the
- option, the val is the path specified for the option,
- and the env is the env to which the Otions have been
- added.
-
-Usage example:
-
- Examples:
- prefix=/usr/local
-
- opts = Variables()
-
- opts = Variables()
- opts.Add(PathVariable('qtdir',
- 'where the root of Qt is installed',
- qtdir, PathIsDir))
- opts.Add(PathVariable('qt_includes',
- 'where the Qt includes are installed',
- '$qtdir/includes', PathIsDirCreate))
- opts.Add(PathVariable('qt_libraries',
- 'where the Qt library is installed',
- '$qtdir/lib'))
