<para>LCDproc is open source software. Anyone is free to take LCDproc's code, write
his own driver and publish the modified sources somewhere again. If you want your

It was decided pretty early in LCDproc's life to use GNU autoconf and GNU automake. This allows LCDproc to be ported to several platforms with much less effort. It can be quite daunting to understand how autoconf &amp; automake interact with each others and with your code, but don't be discouraged. We have taken great care in making this as simple as possible for programers to add their own driver to LCDproc. Hopefully, you'll only have to modify two files, one for autoconf and one for automake.

The first thing you need to do is to find a name for your driver, it should be as descriptive as possible; most drivers are named after their respective chipset, for example hd44780, mtc_s16209x, sed1330 and stv5730, others are named after the company that makes that particular LCD display, for example CFontz and MtxOrb. Remember that these names are case sensitive. In this chapter, we'll use myDriver (which is an absolute non-descriptive name).
