# The run method takes a command to execute and a string of parameters
# that get passed to it. The command is prefixed with the :command_path
# option from Paperclip.options. If you have many commands to run and
# they are in different paths, the suggested course of action is to
# symlink them so they are all in the same directory.
#
# If the command returns with a result code that is not one of the
# expected_outcodes, a PaperclipCommandLineError will be raised. Generally
# a code of 0 is expected, but a list of codes may be passed if necessary.
#
# This method can log the command being run when 
# Paperclip.options[:log_command] is set to true (defaults to false). This
# will only log if logging in general is set to true as well.
