\ProvidesFile ¶Synopsis:
\ProvidesFile{filename}[info-text]
Declare a file other than the main class and package files, such as a
configuration or font definition file. It writes the given
information to the log file, essentially like \ProvidesClass
and \ProvidesPackage (see the previous section).
For example:
\ProvidesFile{smcmemo.cfg}[2017/10/12 config file for smcmemo.cls]
writes this into the log:
File: smcmemo.cfg 2017/10/12 config file for smcmemo.cls
