FFmpeg currently uses a custom build system, this text attempts to document
some of its obscure features and options.

Options to make:
make V=1 <target>
    Build target with verbosity 1, instead of 1, 2 can be used too
make SAMPLES=<path to the fate samples> <target>
    specify the path to the fate samples at make time


Useful standard make commands:
make -t <target>
    Touch all files that otherwise would be build, this is useful to reduce
    unneeded rebuilding when changing headers, but note you must force rebuilds
    of files that actually need it by hand then.

make -j<num>
    rebuild with multiple jobs at the same time. Faster on multi processor systems

make -k
    continue build in case of errors, this is useful for the regression tests
    sometimes but note it will still not run all reg tests.


Targets to make:
fate-list
    Will list all fate/regression test targets

fate
    Run the fate test suite, note you must have installed it


Setting up local fate:
use the following command to get the fate test samples
rsync -aL rsync://rsync.mplayerhq.hu:/samples/fate-suite/ fate/fate-suite
pass --samples=<path to the samples> to configure or pass the path with the
SAMPLES variable to make
