Release build version data.

===========================

 * Build number.

 * Build date.

 * Build version.

 * Branch-tag used.

 * Overnight build (Y/N).

 * QA tested (Y/N).

 * QA test results (Pass/Fail).

 * Location of full logs.

Order formula.

==============

if (A.major != B.major) return A.major > B.major;

if (A.minor != B.minor) return A.minor > B.minor;

if (A.patch != B.patch) return A.patch > B.patch;

if (A.special == B.special) return 0;

if (A.special == "") return 1;

if (B.special == "") return -1;

return A.special > B.special;

**NOTE** Accoding to this definition 1.0.1rc1 < 1.0.1rc10 < 1.0.1rc2 which is

non meaningful.

Compatibility formula.

======================

Assume that app linked with new version of lib. Thus::

  is_compatible_with_old(old, new) {

    if (old.major != new.major) return 0;

    if (old.minor > new.minor) return 0;

    return 1;

  }

Assume that app linked with old version of lib. Thus::

  is_compatible_with_new(old, new) {

    if (old.major != new.major) return 0;

    return 1;

  }
