SEPE-1058: Add patch file support and document SEPE fork

README.md

@@ -3,6 +3,27 @@
 This GitHub Action builds RPMs from spec file and using repository contents as source (wraps the rpmbuild utility).
 Integrates easily with GitHub actions to allow RPMS to be uploaded as Artifact (actions/upload-artifact) or as Release Asset (actions/upload-release-asset).
 
+## SEPE Fork Notice
+
+This repository is a fork of [`naveenrajm7/rpmbuild`](https://github.com/naveenrajm7/rpmbuild),
+created on 2024-02-12 to carry CU Boulder OIT Platform Engineering (SEPE)
+modifications. It is used by the `oit-sepe-naemon-build` pipeline (and any
+other SEPE repos that build RPMs via GitHub Actions). Upstream has been
+effectively dormant since November 2022, so this fork is intentionally not
+tracked against upstream — changes land here directly.
+
+SEPE-specific modifications on top of upstream:
+
+- **AlmaLinux 8 base image.** Switched the Dockerfile from CentOS to AlmaLinux 8,
+  replaced `yum` with `dnf`, enabled the `powertools` repository, pinned Python
+  to `python39`, and bumped the Node.js tooling used to build the action.
+- **Patch file support.** `src/main.ts` copies any `*.patch` files from the
+  repo root into `/github/home/rpmbuild/SOURCES/` before invoking `rpmbuild`,
+  so spec files can reference them via standard `Patch0:`/`Patch1:`/...
+  declarations. No-op if the repo has no patch files.
+
+Before making further changes, verify the divergence from upstream
+(`naveenrajm7/rpmbuild`) and update this notice.
