mkcp2.sh

#!/usr/bin/env bash
#
# This builds the CiderPress II command-line utility ("cp2").  You must have
# the .NET SDK installed (this uses the "dotnet build" command).
#
# Usage:
#  mkcp2.sh [--runtime RUNTIME] [--debug] [--self-contained]
#
# By default, this will do a release build for the current operating system
# and CPU architecture.  You can override the runtime by specifying the
# target RID, which should be something like "win-x64" or "linux-arm64"
# (see https://learn.microsoft.com/en-us/dotnet/core/rid-catalog for details).
#
# For self-contained builds, the runtime must be specified explicitly.
#

# There doesn't appear to be a way to query the system's RID.  If you don't
# specify one, it creates a "portable, framework-dependent app", which is fine.
