# In post-install, we use the manifests generated during Rust install
# to in turn generate the PLIST. We do that, instead of the regular
# `pkg-plist`, because several libraries have a computed filename based
# on the absolute path of the source files. As it is user-specific, we
# can't know their filename in advance.
#
# Both rustc and Cargo components install the same README.md and LICENSE
# files. The install process backs up the first copy to install the
# second. Thus here, we need to remove those backups. We also need to
# dedup the entries in the generated PLIST, because both components'
# manifests list them.
#
# We fix manpage entries in the generated manifests because Rust
# installs them uncompressed but the Ports framework compresses them.
