# Prepare the distribution so the tarball can be built and installed without the code generation or documentation tooling: remove
# everything that is not needed to build, generate the code files, copy the man pages and HTML documentation into doc, copy the
# distribution README, and write the dist marker that tells the build to use the shipped generated files.
#
# The generator reads its inputs from the source tree and writes the generated files into the distribution, since the declarations
# it reads are not shipped in the tarball.

# Remove everything that is not needed to build pgbackrest. The trimming is done here rather than with export-ignore in
# .gitattributes so the source archives that GitHub generates for a tag remain complete and can be built by anyone willing to run
# the code generation tooling. Keep src, the root meson files, and LICENSE. The code generation tooling in build and the
# documentation source in doc are removed because the generated files are added below instead. The smoke test (test/smoke.py) and
# the meson.build that runs it are kept so packagers can verify a build; the rest of test is removed.
