# Undocumented Features

This chapter covers some undocumented features of `hsc`. Most of them are hardly tested, some of them are rather inconsistent. Also, I did not make much effort to explain them very well.

## Options File

On startup, `hsc` will look for an options file, which will be parsed for command line options before the actual command line options passed from CLI. Values set in the options file can be overwritten by command line options later.

The format of the options file is easy as can be: it consists of several lines, with every line containing one single options, and, if necessary, also a ```=`'' and a value. An example options file could look like this:

        FROM=include/stdmacros.hsc
        TO=www:sepp/
        COMPACT
        IGNORE=note|style

The options file always has to be named hsc.options.
