PERCEPS, Perl C++ Surveyor, is an automatic documentation generator for C++. PERCEPS is a Perl script designed to parse C/C++ header files and automatically generate documentation in a variety of formats based on the class definitions, declarations, and comment information found in those files. Using this tool allows programmers to comment their code and generate useful documentation at the same time with no extra effort. PERCEPS can be useful both as a documentation tool and a simple but effective collaboration tool for both C and C++ projects.
