# USAGE: ./dist.sh -v VERSION -r REVISION -d RELEASE_DATE
#                  [-rs REVISION-SVN] [-pr REPOS-PATH]
#                  [-win] [-alpha ALPHA_NUM|-beta BETA_NUM|-rc RC_NUM]
#
#   Create a distribution tarball, labelling it with the given VERSION.
#   The REVISION or REVISION-SVN will be used in the version string.
#   The tarball will be constructed from the root located at REPOS-PATH.
#   If REPOS-PATH is not specified then the default is "branches/VERSION".
#   For example, the command line:
#
#      ./dist.sh -v 0.24.2 -r 6284 -d 2/7/05
#
#   from the top-level of a branches/0.24.2 working copy will create
#   the 0.24.2 release tarball.
#
#   When building a alpha, beta or rc tarballs pass the appropriate flag
#   followed by the number for that release.  For example you'd do
#   the following for a Beta 1 release:
#      ./dist.sh -v 1.1.0 -r 10277 -pr branches/1.1.x -beta 1
# 
#   If neither an -alpha, -beta or -rc option with a number is
#   specified, it will build a release tarball.
#  
#   To build a Windows package pass -win.
