Annotation of embedaddon/dnsmasq/bld/get-version, revision 1.1.1.5

2:
3: # Determine the version string to build into a binary.
4: # When building in the git repository, we can use the output
5: # of "git describe" which gives an unequivocal answer.
6: #
7: # Failing that, we use the contents of the VERSION file
8: # which has a set of references substituted into it by git.
9: # If we can find one which matches $v[0-9].* then we assume it's
10: # a version-number tag, else we just use the whole string.
11: # If there is more than one v[0-9].* tag, sort them and use the
1.1.1.5 ! misho 12: # first. The insane arguments to the sort command are to ensure
! 13: # that, eg v2.64 comes before v2.63, but v2.63 comes before v2.63rc1
! 14: # and v2.63rc1 comes before v2.63test1
