The string is appropriate for use in installations and +# distributions. Currently this script assumes we are using git as our +# version control system but it would be possible to check and see if we +# are using an alternative version control system and create a version +# string appropriately. +# +# The script uses git describe plus a few other git commands to create a +# version strings in the following format: +# +# X.Y[-Z-gN][-dirty] +# +# where X is the major release, Y is the minor release, Z is the number +# of commits since the X.Y release, N is an eight digit abbreviated SHA +# hash of the most recent commit and the dirty suffix is appended when +# the working directory used to create the installation or distribution +# is not a pristine checkout. Here are some example version strings: +# +# 0.0 : initial import +# 0.0-3-g99ef6933 : 3rd commit since initial import (N=99ef6933) +# 1.0 : release 1.0 +# 1.1-12-g3487ab12 : 12th commit since release 1.1 (N=3487ab12) +# 1.1-12-g3487ab12-dirty : 12th commit since release 1.1 (N=3487ab12) +# +# The last example is from a dirty working directory. To find the last +# release, the script looks for the last tag (does not need to be an +# annotated tag, but probably should be) which matches the format rel-*. +# If there is no such tag in the history, then the script uses 0.0 as +# the release number and counts the total number of commits since the +# original import for the commit count. +# +# If the current directory is not within the working directory, then the +# path to the source directory should be supplied on the command line. +# +# Author : Christopher Batten +# Date : August 5, 2009 + +set -e + +#------------------------------------------------------------------------- +# Command line parsing +#------------------------------------------------------------------------- + +if ( test "$1" = "-h" ); then + echo "" + sed -n '3p' $0 | sed -e 's/#//' + sed -n '5,/^$/p' $0 | sed -e 's/#//' + exit 1 +fi + +# Source directory command line option + +src_dir="." +if ( test -n "$1" ); then + src_dir="$1" +fi + +#------------------------------------------------------------------------- +# Verify source directory +#------------------------------------------------------------------------- +# If the source directory is not a git working directory output a +# question mark.
