class Source
# This class is used to read source paths from a (gzipped) tar archive. The archive can be remote
# (http(s) or ftp) or local.
#
# For example, the following are all valid URIs:
# http://example.com/directory/file.tgz
# /home/test/my.tar.gz
# ftp://ftp.example.com/archives/archive.tar
#
class TarArchive
# The URI of the tar archive.
attr_reader :uri
# The glob (see File.fnmatch for details) that is used to specify which paths in the archive should
# be returned by #paths.
attr_reader :glob
# Create a new tar archive source for the URI string +uri+.
