# FORCE NOARCH
# This package is noarch intentionally, although it supplies binaries,
# as they're not intended for the build platform, but for AVR.

%description
AVR Libc is a Free Software project whose goal is to provide a high quality C
library for use with GCC on Atmel AVR microcontrollers.

AVR Libc is licensed under a single unified license. This so-called modified
Berkeley license is intented to be compatible with most Free Software licenses
like the GPL, yet impose as little restrictions for the use of the library in
closed-source commercial applications as possible.

%description doc
This package contains the AVR C library docs in html and pdf format, the main
package already contains the docs in man-page format (use "avr-man xxxx" to
access these).
