\maketitle

This example demonstrates the use of the new macros for declaring
class and package options of the \textsf{xkeyval} package. Please
study the files \verb+xkvex2.tex+, \verb+xkveca.cls+,
\verb+xkvecb.cls+, \verb+xkvesa.sty+, \verb+xkvesb.sty+ and
\verb+xkvesc.sty+ carefully to understand the output below.\\

Set by \verb+xkveca.cls+: \keyi\par
Set by \verb+xkvesa.sty+, copied from \verb+\documentclass+: \keyia\par
Set by \verb+xkvesa.sty+: \keyii\par
Set by \verb+xkvesb.sty+, passed on from \verb+xkvesa.sty+: \keyiii\par
Set by \verb+xkvesb.sty+, passed on as unknown key from \verb+xkvesa.sty+: \keyiv\par
Set by \verb+xkvesb.sty+, passed on as unknown from \verb+xkvesa.sty+: \keyv\par
Set by the class, copied by \verb+xkvesc.sty+: \keyvi\par
Set by \verb+xkvesc.sty+: \keyvii\par
Set by \verb+xkvecb.cls+, passed on from \verb+xkveca.cls+: \keyviii\\

The document class is: \XKV@documentclass\par
Unused global options: \@tempb\\

Notice the content of the following macros.\par
\verb+\@classoptionslist+: \@tempa\par
\verb+\XKV@classoptionslist+: \XKV@classoptionslist\\

This shows that \verb+key=value+ pairs have been deleted from the
class options list so that subsequent packages which are not using
\textsf{xkeyval} and are scanning this list will not run into
problems.\\
