<P> The first group of commands discussed here are those used to identify your class or package file.

This command tells T<SMALL>E</SMALL>X that this file should be processed using a
format with name format-name. You can use the optional argument
release-date to further specify the earliest release date of the
format that is needed. When the release date of the format is older
than the one specified a warning will be generated. The standard
format-name is <TT>LaTeX2e</TT>. The date, if present, must be in
the form <SMALL>YYYY/MM/DD</SMALL>.
<P> Example: <PRE> </PRE>

This declares that the current file contains the definitions for the
document class class-name or package package-name.
<P> The optional release-info, if used, must contain:
<UL> <LI>the release date of this version of the file, in the form <SMALL>YYYY/MM/DD</SMALL>; </LI> <LI>optionally followed by a space and a short description, possibly including a version number. </LI> </UL> The above syntax should be followed exactly so that this information can be used by || or | (for classes) or |or | (for packages) to test that the release is not too old.
<P> The whole of this release-info information is displayed by || and should therefore not be too long.
<P> Example: <PRE> </PRE>

This is similar to the two previous commands except that here the full
filename, including the extension, must be given. It is used for
declaring any files other than main class and package files.
<P> Example: <PRE> </PRE>
