# publish.sh — Linux/macOS counterpart of publish.ps1.
#
# Publishes the Mbproxy binary in two flavours for the requested runtime under
# <repo>/publish-out/:
#
#   self-contained/        ~100 MB — bundles the .NET 10 + ASP.NET Core runtime;
#                                    no .NET install needed on the target.
#   framework-dependent/   ~1.6 MB — requires the .NET 10 + ASP.NET Core runtime
#                                    preinstalled on the target.
#
# Each folder also receives a current appsettings.json — the platform-appropriate
# install template (Windows or Linux, selected by -r RID) — so every publish-out
# flavour is a complete, deployable folder.
#
# Both builds use the Release configuration and inherit the publish settings in
# src/Mbproxy/Mbproxy.csproj (those settings are gated on an explicit RID, which
# is supplied here). The framework-dependent build overrides SelfContained=false.
#
# Usage:
#   ./publish.sh [-r RID] [-o OUTPUT_DIR] [--clean]
#
#   -r RID          .NET runtime identifier (default: linux-x64)
#   -o OUTPUT_DIR   root output directory (default: <repo>/publish-out)
#   --clean         delete OUTPUT_DIR before publishing
#
# Examples:
#   ./publish.sh
#   ./publish.sh -r linux-x64 --clean
#
