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