Awesome!

Would you mind, however, to relicense the code under a license compatible with GPLv2? Currently your code is under the Apache License (which I heard somewhere is probably incompatible with the GPLv2 used by the Git project): https://github.com/google/reftable/blob/6cd8dbb4106d18627f442d3148de71d7db43d4b6/c/api.h#L1-L13

Thanks, Dscho

according to our open source lawyers, Apache is actually compatible with GPLv2, but I think we could dual-license the code.

The GNU website [0] says:
  Apache License, Version 2.0
    This is a free software license, compatible with version 3 of the GNU GPL.
    Please note that this license is not compatible with GPL version 2, 
    because it has some requirements that are not in that GPL version. 
    These include certain patent termination and indemnification 
    provisions. The patent termination provision is a good thing, which 
    is why we recommend the Apache 2.0 license for substantial programs 
    over other lax permissive licenses.
