24 * The following part of the code determines the CLIENT_BUILD variable.
25 * Several mechanisms are used for this:
26 * * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
27 * generated by the build environment, possibly containing the output
28 * of git-describe in a macro called BUILD_DESC
29 * * secondly, if this is an exported version of the code, GIT_ARCHIVE will
30 * be defined (automatically using the export-subst git attribute), and
31 * GIT_COMMIT will contain the commit id.
32 * * then, three options exist for determining CLIENT_BUILD:
33 * * if BUILD_DESC is defined, use that literally (output of git-describe)
34 * * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
35 * * otherwise, use v[maj].[min].[rev].[build]-unk
36 * finally CLIENT_VERSION_SUFFIX is added
