-#X text 19 146 2) Zero or more elements \, which may be any atom type
-that Pd can understand.;
-#X text 19 106 Messages in Pd are made up of the following components:
-;
-#X text 19 183 Messages divide into two groups: those with selectors
-that have a predefined meaning and behavior in Pd \, and everything
-else. See the other subpatches for more on how Pd processes messages.
-;
-#X text 19 36 Objects in Pd send each other various data in the form
-of messages. Messages can transport all kinds of information: float
-\, symbol \, and pointer atoms \, groups of floats and symbols \, etc.
-Understanding how to build and work with messages is a key to understanding
