EStdStringTokenizer:
License: see the file LICENSE in this directory.
Author: stephan@wanderinghorse.net
Based heavily off of work by:
Martin Jones (mjones@kde.org)
Torben Weis (weis@kde.org)
Waldo Bastian (bastian@kde.org)
which i originally found as StringTokenizer in the KDE 1.x
source tree. i have received explicit permission from each
of those gentlemen to release the StringTokenizer code into
into the Public Domain. (Many thanks to them for that
permission, without which this whole library would
necessarily be released under the GNU GPL.)
This class is meant to be API- and behaviour-compatible
with StringTokenizer. This implementation is, however, MUCH
less efficient.
EStdStringTokenizer tokenizes strings in a way which is
consistent with the way a Unix shell does. This makes it
appropriate for use in parsing many types of arbitrary user
input, from command-line arguments to comma-separated
files.
