# upstream sources (jaokim's JamVM + IcedTea 8) that are gitignored here, and the
# clib4 C runtime is the in-repo clib4/ git submodule (AmigaLabs/clib4,
# `development`) that `make build` checks out automatically.  No external paths.
#
# Windows: run from PowerShell (the Git-Bash MSYS layer mangles docker paths).
