# The Linux packages (P11a step 3), from the release program already built
# at target/release/wanderbooks (`cargo build --release -p ledger-cli`).
#
#   build-linux.sh [VERSION] [FORMATS]
#
# Puts into target/packages/VERSION/: the .deb, the AppImage and the
# pacman tarball with its PKGBUILD (cargo-packager), and the .rpm
# (cargo-generate-rpm). VERSION defaults to the program's own; a different
# one repackages the same program under that version, which is how the
# install-and-upgrade test gets its second release. FORMATS is
# cargo-packager's list (default deb,appimage,pacman); the .rpm is always
# built. Run from the repository root.
#
# The program is target/release/wanderbooks, or the file WB_PROGRAM names:
# a package must run on the oldest system it claims, and a program linked
# on a newer one (this machine's glibc) fails there with "GLIBC_2.43 not
# found". CI builds on ubuntu-24.04; `just test-linux-packages` builds in a
# Debian trixie container.
