+/*
+General Description:
+This header is intended to contain all (or at least most of) the compiler
+and library dependent stuff. The C code is written for avr-gcc and avr-libc.
+The API of other development environments is converted to gcc's and avr-libc's
+API by means of defines.
+
+This header also contains all system includes since they depend on the
+development environment.
+
+Thanks to Oleg Semyonov for his help with the IAR tools port!
