TODO list
=========

When options.yy reports an error, file name and line number should be reported
as well (as GNU standards).

Do not use sed anymore for avoiding name conflicts for flex and bison:
use the command line option.

cpp2html <path>/*.c : ouput files are created in <path> instead of the
current directory (is it correct?)

Texinfo documentation.

for read_file use a class to initialize with the name of the
package

fix gengetopt in order to print the right package

When help is printed
Usage: source-highlighter [OPTIONS]... [FILES]... 
is it OK?
