What is the purpose of the * .pro file?

Question

I just started using Qt and noticed that there is a file in every example code folder .pro(and there is also a make file ... why?). What is the purpose of the file .pro?

Answer 1

This is a multi-platform project file that qmaketurns into platform-specific program files. The main reason for its existence is the simplified configuration and compilation of multi-platform projects. Compare, for example. to autotools scripts configureand makefiles that are commonly found in unixland.
