# rbenv local --unset
#
# Sets the local directory-specific Ruby version by writing the version
# name to a file named `.rbenv-version'.
# name to a file named `.ruby-version'.
#
# When you run a Ruby command, rbenv will look for an `.rbenv-version'
# When you run a Ruby command, rbenv will look for a `.ruby-version'
# file in the current directory and each parent directory. If no such
# file is found in the tree, rbenv will use the global Ruby version
# specified with `rbenv global', or the version specified in the
# RBENV_VERSION environment variable.
#
# For backwards compatibility, rbenv will also read version
# specifications from `.rbenv-version' files, but a `.ruby-version'
# file in the same directory takes precedence.
#
# <version> should be a string matching a Ruby version known to rbenv.
# The special version string `system' will use your default system Ruby.
# Run `rbenv versions' for a list of available Ruby versions.
