<partintro>
<simpara>
This extension allows you to process credit cards transactions using
Crédit Mutuel CyberMUT system (
<ulink url="&url.cybermut;">&url.cybermut;</ulink>).
</simpara>
<simpara>
CyberMUT is a popular Web Payment Service in France, provided by the
Crédit Mutuel bank. If you are foreign in France, these functions will not
be useful for you.
</simpara>
<simpara>
These functions are only available if PHP has been compiled with the
<link linkend="install.configure.with-cybermut"><option role="configure">
--with-cybermut[=DIR]</option></link>
option, where DIR is the location of <filename>libcm-mac.a</filename>
and <filename>cm-mac.h</filename>.
You will require the appropriate SDK for your platform, which
may be sent to you after your CyberMUT's subscription (contact
them via Web, or go to the nearest Crédit Mutuel).
</simpara>
<simpara>
The use of these functions is almost identical to the original functions,
except for the parameters of return for <function>cybermut_creerformulairecm</function>
and <function>cybermut_creerreponsecm</function>,
which are returned directly by functions PHP, whereas they had passed in
reference in the original functions.
</simpara>
<simpara>
These functions have been added in PHP 4.0.6.
</simpara>
<note>
<para>
These functions only provide a link to CyberMUT SDK. Be sure to read the
CyberMUT Developers Guide for full details of the required parameters.
