# publish.sh  --  package src/Script_ABC_Blanton for delivery
# =============================================================================
# Version History:
#   V1.0.0  2026-08-21  Initial. Copies src/Script_ABC_Blanton to
#                       publish/Script_ABC_Blanton_<Version>, taking <Version>
#                       from the "; Version : Vx.y.z" header of
#                       1_Blanton_Script_A.ttl.
# =============================================================================
#
# The version is READ FROM Script A rather than passed in, so the folder name
# can never disagree with the header the tester sees when they open the macro.
# Bump Script A's header first, then run this.
#
# Usage:
#   ./publish/publish.sh              # publish at Script A's version
#   ./publish/publish.sh -v V1.0.4    # override the version
#   ./publish/publish.sh -f           # overwrite an existing output folder
#   ./publish/publish.sh -z           # also produce a .zip next to it
#   ./publish/publish.sh -n           # dry run: print what would happen
# =============================================================================
