// Description : This is a convenience class to specialize
|
|
// ConfigVariable as a Filename type. It is almost the
|
|
// same thing as ConfigVariableString, except it handles
|
|
// an implicit Filename::expand_from() operation so that
|
|
// the user may put OS-specific filenames, or filenames
|
|
// based on environment variables, in the prc file.
