/**
* Test style rules by converting to a text format, rather than a .img file.
* In addition you can specify a .osm file and a style file separately.
*
* <h2>Single test file</h2>
* The format of the file is as follows
*
* <pre>
* WAY 42
* highway=primary
* oneway=reverse
*
* <<<lines>>>
* highway=primary [0x3 road_class=2 road_speed=2]
* power=line [0x29 resolution 20]
* </pre>
*
* You can have any number of ways, each must end with a blank line.
* A way will be created with two points (1,1),(2,2) (so you can see the
* action of oneway=reverse) and the tags that you specify. If you give
* a number after WAY it will be printed on output so that if you have more
* than one you can tell which is which. If the number is omitted it will
* default to 1.
*
* You can have as many rules as you like after the <<<lines>>> and you
* can include any other style files such as <<<options>>> or <<<info>>> if
* you like.
*
* <h2>osm file mode</h2>
* Takes two arguments, first the style file and then the osm file.
*
* You can give a --reference flag and it will run style file in reference mode,
* that is each rule will be applied to the element without any attempt at
* optimisation. This acts as an independent check of the main style code
* which may have more optimisations.
