1298 *** The color-gcc wrapper
1299
1300 This wrapper colorizes the error messages from gcc. By default XEmacs
1301 does not interpret the escape sequences used to generate colors,
1302 resulting in a cluttered, hard-to-read buffer. You can remove the
1303 wrapper, or defeat the wrapper colorization in Emacs process buffers
1304 by editing the "nocolor" attribute in /etc/colorgccrc:
1305
