# USAGE: ./dist.sh -v VERSION -r REVISION [-rs REVISION-SVN] [-pr REPOS-PATH]
#                  [-apr PATH-TO-APR ] [-apru PATH-TO-APR-UTIL] 
#                  [-apri PATH-TO-APR-ICONV] [-neon PATH-TO-NEON]
#                  [-zip] [-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
#
#   from the top-level of a branches/0.24.2 working copy will create
#   the 0.24.2 release tarball. Make sure you have apr, apr-util,
#   and neon subdirectories in your current working directory or
#   specify the path to them with the -apr, -apru or -neon options.
#   For example:
#      ./dist.sh -v 1.1.0 -r 10277 -pr branches/1.1.x \
#        -apr -neon ~/in-tree-libraries/neon-0.24.7 \
#        -apr ~/in-tree-libraries/httpd-2.0.50/srclib/apr \
#        -apru ~/in-tree-libraries/httpd-2.0.50/srclib/apr-util/
#
#   When building a alpha, beta or rc tarballs pass the apppropriate flag
#   followeb by the number for that releasse.  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 zip file package pass -zip and the path
#   to apr-iconv with -apri.
