# newver
#
# Shell script to 'create' a new version of software within
# the BaBar code system
#
# Bob Jacobsen Sept 1994
#
# Function:
#   Check in correct directory ($BFDIST/packages/<package>) (*)
#   Check version does not exist
#   CVS export the tagged code
#   Touch all files with the current date
#   Mark all files read only
#
# Items with a (*) are not yet implemented
#
# Options:
#   -v  Tells you the version, then quits.
#   -p  This will be a production version.
# 	This must be explicitly specified, even though -t is not allowed.
#   -R  Passed to cvs to control remote export
#   -d CVS-root-directory  Get package from CVS-root-directory
#                            (same as -d option in cvs)
#
# Arguments
#   <tag>       CVS tag to use
#
# 19981103	kreymer
#    UPS declare using $BFDIST only when $PROJECT_DIR/.experiment contains CDF
#
# 19981208  Amundson
#    Added -d option.
#    Special case for using newver on SoftRelTools itself:
#      SRTsite.(c)sh and arch_spec_site.mk files are now copied from the
#      release "current" iff they exist.
