Add automated ET:Legacy i386 server build workflow
This workflow automates the creation of a LinuxGSM-compatible archive by combining the latest ET:Legacy i386 server binary with original Enemy Territory 2.60b pak files. It handles version scraping, binary renaming, and weekly release publishing.

# etlserver-build
2+
3+
Automated GitHub Actions build that combines the latest
4+
[ET:Legacy](https://www.etlegacy.com/) Linux i386 server with the original
5+
Enemy Territory 2.60b game files, producing a single archive ready for use
6+
with [LinuxGSM etlserver](https://linuxgsm.com/servers/etlserver/).
7+
8+
## Why this exists
9+
10+
ET:Legacy requires both its own server binary **and** the original Enemy
11+
Territory pak files (`pak0.pk3`, `pak1.pk3`, `pak2.pk3`) to run. LinuxGSM
12+
currently ships an i386 combined package, but this repo automates keeping it
13+
up to date with the latest ET:Legacy release.
14+
15+
## What the workflow does
16+
17+
1. Scrapes `https://www.etlegacy.com/download` to find the latest stable
18+
Linux i386 archive URL.
19+
2. Checks whether a release already exists for that version — skips the build
20+
if it does.
21+
3. Downloads the ETL Linux x86_64 archive and the Enemy Territory 2.60b files.
22+
4. Renames `etlded.i386` → `etlded` for LinuxGSM compatibility.
23+
5. Merges the original ET `pak*.pk3` files into `etmain/`.
24+
6. Packages everything into a flat `etlegacy-vX.Y.Z-i386-et-260b.tar.xz`
25+
archive and publishes a GitHub Release.
26+
27+
## Schedule
28+
29+
The workflow runs every **Monday at 02:00 UTC** and can also be triggered
30+
manually via `workflow_dispatch`.
31+
32+
## Using the release with LinuxGSM
33+
34+
Update the `etl` entry in LinuxGSM's `install_server_files.sh` to point at
35+
the release asset URL shown in the release notes, e.g.:
36+
37+
```
38+
https://github.com/GameServerManagers/etlserver-build/releases/download/vX.Y.Z/etlegacy-vX.Y.Z-x86_64-et-260b.tar.xz
39+
```
