CI configuration for Elasticsearch
==================================

Layout and Syntax
-----------------

CI is run by Jenkins at [elasticsearch-ci](https://elasticsearch-ci.elastic.co/).
Jobs live in the [jobs.t](jobs.t) directory, these are defined in YML using a syntax 
simmilar to [JJB](https://elasticsearch-ci.elastic.co/view/Elasticsearch%20master/).
Macros are not allowed, and each job must be defined in its own file.

        byte[] ctx = new byte[0x40];
        int ci = 0;
        SMBUtil.writeInt4(0, ctx, ci); // Next = 0
        ci += 4;
        SMBUtil.writeInt2(0x10, ctx, ci); // NameOffset
        SMBUtil.writeInt2(4, ctx, ci + 2); // NameLength
        ci += 4;
        SMBUtil.writeInt2(0, ctx, ci); // Reserved
        SMBUtil.writeInt2(0x20, ctx, ci + 2); // DataOffset
        ci += 4;
        SMBUtil.writeInt4(8, ctx, ci); // DataLength
