arduino-builder - 1.3.25-2+b5 main

This tool is able to parse Arduino Hardware specifications, properly run 'gcc'
and produce compiled sketches.
.
An Arduino sketch differs from a standard C program in that it misses a 'main'
(provided by the Arduino core), function prototypes are not mandatory, and
libraries inclusion is automagic (you just have to #include them). This tool
generates function prototypes and gathers library paths, providing 'gcc' with
all the needed '-I' params.
