make

Recompile all files that have been modified since their last compilation.

Description

This is a simple utility which uses file modification times to determine if a file needs recompilation. All compiled files in the system are examined and recompiled if they have been modified since the previous compilation. make/0 can be defined as follows: 

make :- current_compiled_file(File, Time, Module),
        get_file_info(File, mtime) =\= Time,
        compile(File, Module),
        fail.
make.
