Automake is a tool provided by GNU for the purpose of automating the generation of portable, configurable Makefiles.
Autotools is a suite of programming tools (mainly autoconf, automake, and libtool) designed to assist in making source-code packages portable to many Unix-like systems.
|Slightly more complicated||
"In the case of autotools it is slightly more complicated because not everybody who compiles the software would need automake and autoconf installed only those that need to change the build system adding new files counts as changing the build system"
