Output: <REV>\t<REV_NR>\t<MODIFIED>\t<CLEAN_REV> REV a string describing what version of the code the current checkout is based on. The exact format of this string depends on the version control system in use, but it tries to identify the revision used as close as possible (using the svn revision number or hg/git hash). This also includes an indication of whether the checkout was modified and which branch was checked out. This value is not guaranteed to be sortable, but is mainly meant for identifying the revision and user display. If no revision identifier could be found, this is left empty. REV_NR the revision number of the svn revision this checkout is based on. This can be used to determine which functionality is present in this checkout. For trunk svn checkouts and hg/git branches based upon it, this number should be accurate. For svn branch checkouts, this number is mostly meaningless, at least when comparing with the REV_NR from other branches or trunk. This number should be sortable. Within a given branch or trunk, a higher number means a newer version. However, when using git or hg, this number will not increase on new commits. If no revision number could be found, this is left empty. MODIFIED Whether (the src directory of) this checkout is modified or not. A value of 0 means not modified, a value of 2 means it was modified. Modification is determined in relation to the commit identified by REV, so not in relation to the svn revision identified by REV_NR. A value of 1 means that the modified status is unknown, because this is not an svn/git/hg checkout for example. CLEAN_REV the same as REV but without branch name By setting the AWK environment variable, a caller can determine which version of "awk" is used. If nothing is set, this script defaults to "awk".
