// Description : This class stores a list of directories that can be
|
||
|
|
// searched, in order, to locate a particular file. It
|
||
|
|
// is normally constructed by passing it a traditional
|
||
|
|
// searchpath-style string, e.g. a list of directory
|
||
|
|
// names delimited by spaces or colons, but it can also
|
||
|
|
// be built up explicitly.
