In this example some variables of the style __VAR__ are taken from the macro definition file. A macro with arguments of the style __MYMACRO__(myarg1 myarg2) is used to define the font style of the text. Note that the arguments are accessed as __1__ and __2__ in the macrodefinition file. One set of output files is generated whenever the pseudo macro definition __EVAL__ is encountered in the macro definition file. An implicit __EVAL__ is appended to the end of the macro definition file if none is present. The name of the output file is generated by appending the contents of the macro __NAME__ to the name of the input file (original extension is preserved).

• macro.def - macro definition file
• source/main.html - HTML source file
• do_test - how the program is called
• target/mainen.html - first output file
