\subsubsection{Obtaining a module id and registering the module}
As discussed in chapter \ref{sec:cts_slow_control}, the software identifies the capabilities of any given CTS by enumerating
over a sequence of module headers each containing a module id. The software then loads the drivers located in
- \filename{daqtools/web/CtsPlugins/CtsMod<lower-case-hex-id>.pm}. This is also the central database of module ids. Just choose
+ \files{daqtools/web/CtsPlugins/CtsMod<lower-case-hex-id>.pm}. This is also the central database of module ids. Just choose
a free number, use the template shown in listing \ref{lst:cts_howto_driver_template}) to create a new driver and check it in,
to ensure nobody else takes this id.
