9Source code layout:
10
11auxiliary/ - design tools.
12build/ - build directory (created by make).
13math/ - math library source.
14math/include/ - math library public headers.
15math/single/ - code for cpu with only single precision support.
16test/ - test related source.
17test/rtest/ - test generator (requires mpfr and mpc).
18test/testcases/ - test cases.

20The steps to build the library and run the tests:
21
22cp config.mk.dist config.mk
23# edit config.mk if necessary ...
24make
25make check
26
27Or building outside of the source directory:
28
29ln -s path/to/src/Makefile Makefile
30cp path/to/src/config.mk.dist config.mk
31echo 'srcdir = path/to/src' >> config.mk
32# further edits to config.mk
33make
34make check
35
36The test system requires libmpfr and libmpc.
37
38For cross build, CROSS_COMPILE should be set in config.mk and EMULATOR
39should be set for cross testing (e.g. using qemu-user or remote access
40to a target machine), see the examples in config.mk.dist.
41
42The script "remez.jl" was used to generate some of the coefficients
43(see comments in the code).
