the file "COPYING" for details).

To compile under Linux or FreeBSD (and possibly other operating
systems which I haven't tested), run:

If it doesn't work, try:

To run:

./gentr1

....

./gentr4

A track will be generated, based on an input file. For instance,
"trk1" was the input file for "track1". The resulted file must be
then edited (with a text editor) to correct the number of objects
(around line 36) and also to make any other interesting
modifications.

The structure of the input file is:

n1 t1
n2 t2
....
....

where t1, t2, ... are types of track elements and n1, n2, ... are
the numbers of times each track element is repeated.

The types of track elements are:

0 - straight, horizontal
1 - 22.5 degrees right, horizontal
2 - 45 degrees right, horizontal
3 - 22.5 degrees left, horizontal
4 - 45 degrees left, horizontal
5 - straight, slope 2:25
6 - straight, slope 4:25
7 - straight, slope 6:25
8 - straight, slope -2:25
9 - straight, slope -4:25
10 - straight, slope -6:25
11 - tunnel start, horizontal
12 - tunnel, horizontal
13 - tunnel end, horizontal
14 - bridge start, slope 6:25
15 - bridge, horizontal
16 - bridge end, slope -6:25
17 - bridge, slope 6:25
18 - bridge, slope -6:25
19...24 - different types of loops
