## DESCRIPTION

This manual page documents briefly the **sdccp** command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. Instead, you can read the documentation in /usr/share/doc/sdcc-doc.

**SDCC** is a Freeware, retargettable, optimizing ANSI-C compiler designed for 8 bit Microprocessors.
