+.SYNOPSIS
+    Packs all MxAccessGateway clients into a single dist/ directory.
+
+.DESCRIPTION
+    Runs each language client's native packaging command:
+      .NET    -> dotnet pack (NuGet)
+      Python  -> python -m build (sdist + wheel)
+      Rust    -> cargo package (.crate)
+      Java    -> gradle assemble + jars (jar + sources + javadoc + pom)
+      Go      -> skipped; use scripts/tag-go-module.ps1
+
+    All artifacts land in -OutputDir (default: dist/).
+
+    With -Publish, each language pushes its package to the internal Gitea
+    feed. Requires GITEA_USERNAME and GITEA_TOKEN env vars.
+
+.PARAMETER OutputDir
+    Where to drop the packed artifacts. Default: ./dist
+
+.PARAMETER Languages
+    Subset of languages to pack. Default: all five.
+    Values: dotnet, python, rust, java, go
+
+.PARAMETER Publish
+    After packing, upload to Gitea feeds. Requires:
+      GITEA_USERNAME
+      GITEA_TOKEN
+    Will refuse to publish if either is missing.
+
+.PARAMETER SkipTests
+    Skip per-language regression tests before packing. Default: false.
+
