# The service driver for the Shell service. It manages the creation of

#
# Usage:
#
# Net::SSH.start( host ) do |session|
# shell = session.shell.open
#
# shell.cd "/home/foo"
# shell.mkdir "-p some/long/dir"
# shell.cd "some/long/dir"
# shell.touch "foo.txt"
# shell.exit
#
# session.loop
# end
#
# Or:
#
# Net::SSH.start( host ) do |session|
# shell = session.shell.sync
#
# shell.cd "/home/foo"
#
# out = shell.test "-e some/file.txt"
# if out.status == 0
# out = shell.cat "some/file.txt"
# puts out.stdout
# else
# puts "no such file 'some/file.txt'"
# end
