 ## Publishing a build
 
-From the repository root, with the version taken from `Cargo.toml`:
+From the repository root:
 
 ```sh
-V=$(sed -n 's/^version = "\(.*\)"/\1/p' Cargo.toml | head -1)
+./scripts/publish.sh
+```
 
-cargo build --release --target x86_64-unknown-linux-gnu
-cargo build --release --bin client --no-default-features --target i686-unknown-linux-gnu
-cargo build --release --bin client --target x86_64-pc-windows-gnu
+It reads the version from `Cargo.toml`, builds all four artifacts and installs
+them under `web/bin` with the names above. Override the destination with
+`DEST=/srv/www/bin ./scripts/publish.sh`.
 
-cp "target/x86_64-unknown-linux-gnu/release/server"   "web/bin/server/zagan-bet-server-$V-linux-x86_64"
-cp "target/x86_64-unknown-linux-gnu/release/client"   "web/bin/client/zagan-bet-client-$V-linux-x86_64"
-cp "target/i686-unknown-linux-gnu/release/client"     "web/bin/client/zagan-bet-client-$V-linux-i686"
-cp "target/x86_64-pc-windows-gnu/release/client.exe"  "web/bin/client/zagan-bet-client-$V-windows-x86_64.exe"
-```
+Builds are per target triple, so these must be installed:
+`x86_64-unknown-linux-gnu`, `i686-unknown-linux-gnu` and
+`x86_64-pc-windows-gnu`, plus the mingw linker for the Windows build. Client
+builds always pass `--no-default-features`, which drops the server's OpenSSL
+dependency; the client is rustls-only.
 
-`--no-default-features` drops the server's OpenSSL dependency, which is what
-the 32-bit client build would otherwise fail on.
+Cargo itself cannot produce these names: it always writes
+`target/<triple>/release/<bin>`. The script renames after each build.
