+test-qemu with Podman
+=====================
+
+This directory provides some simple scripts for creating and running
+quite small Alpine Linux container images, intended for testing
+statically-linked Linux executables with Podman and qemu-user.
+
+Very short usage instructions follow.
+
+### Where do I get statically-linked Linux binaries:
+  - all recent official UPX linux release binaries are statically linked
+  - the `zigcc linux-musl` artifacts as created by our GitHub Actions CI
+  - many other `linux-musl` binaries are statically linked
+  - many `Go` and some `Rust` programs are statically linked
+
+### PREPARATION OUTSIDE THE CONTAINER:
+
+```sh
+    cd your-upx-top-level-directory
+    mkdir -p tmp
+    cd tmp
+
+    # download official UPX release binaries
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-amd64_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-arm64_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-armeb_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-arm_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-i386_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-mipsel_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-mips_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-powerpc64le_linux.tar.xz
+    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-powerpc_linux.tar.xz
+
+    # and unpack all .tar.xz files
+    for f in ./upx*.tar.xz; do tar -xJf $f; done
+```
+
+### INSIDE THE CONTAINER:
+
+```sh
+    cd /home/upx/src/upx/tmp
+
+    # check that the official UPX release binaries do work
+    qemu-i386 ./upx-4.0.2-i386_linux/upx --version
+    qemu-mips ./upx-4.0.2-mips_linux/upx --version
+    # ...same for more architectures
+
+    # use qemu-mips to unpack the arm64 binary, and then run the unpacked arm64 binary:
+    qemu-mips ./upx-4.0.2-mips_linux/upx -d upx-4.0.2-arm64_linux/upx -o upx-arm64-unpacked
+    qemu-aarch64 ./upx-arm64-unpacked --version
+    # ...same for more architectures
+```
