Including Libraries

We have already seen the include statement. It is a preprocessor directive (i.e. include is not a keyword, it is a directive to the lexer part of ccli that reads in *.ccl files). It tells ccli to read in the file noted in its argument before continuing with the preset file. ccli provides several libraries in $CCL_ROOT/lib, including standard input and output, math functions, list operations, and simple graphics tools. These are described in more detail in Section .
