# Summary: Install a Ruby version using ruby-build
#
# Usage: rbenv install [-f|-s] [-kpv] <version> [-- <configure-args...>]
# rbenv install [-f|-s] [-kpv] <definition-file>
# rbenv install --list
# rbenv install --version
#
# -l, --list List latest stable versions for each Ruby
# -L, --list-all List all local versions, including outdated ones
# -f, --force Allow overwriting an existing installed version
# -s, --skip-existing Avoid overwriting an existing installed version
#
# ruby-build options:
#
# -v, --verbose Verbose mode: forward all build output to stdout/stderr
# -p, --patch Apply a patch from stdin before building
# -k, --keep Keep source tree in RBENV_BUILD_ROOT after installation
# (defaults to "RBENV_ROOT/sources")
# --version Show version of ruby-build
#
# For detailed information on installing Ruby versions with ruby-build,
# including a list of environment variables for adjusting compilation,
# see: https://github.com/rbenv/ruby-build#usage
