    " "The 4cpp lexer system provides a polished, fast, flexible system that " "takes in C/C++ and outputs a tokenization of the text data. There are " "two API levels. One level is setup to let you easily get a tokenization " "of the file. This level manages memory for you with malloc to make it " "as fast as possible to start getting your tokens. The second level " "enables deep integration by allowing control over allocation, data " "chunking, and output rate control.

    " "To use the quick setup API you simply include 4cpp_lexer.h and read the " "documentation at cpp_lex_file.

    " "To use the the fancier API include 4cpp_lexer.h and read the " "documentation at cpp_lex_step. " "If you want to be absolutely sure you are not including malloc into " "your program you can define FCPP_FORBID_MALLOC before the include and " "the \"step\" API will continue to work.
