It's an old children's party game, "Parse the parcel", AKA, "Chinese
Whispers".

Each person hears a whisper, tries to understand it, and then passes it
along as a whisper. At the end of the line, the arrived message is compared
with the original.

Parsers can be many things, but they can be very simple. Here's a list
parser, which will use the characters in Sep to return a list of tokens
.... the Lst_t library is left as exercise for student (so as not to do
*ALL* your homework).

Lst_t *tokens ;

tokens = s_parse( "This is my string", " \t\r" ) ;
lst_dump( tokens ) ;

produces ...
This
is
my
string


Lst_t *s_parse( Str_t Str, Str_t Sep ){
Str_t p, q ;
Lst_t *x ;

if( !Str )
return( (Lst_t *) NULL ) ;

x = lst_create( 10 ) ;
p = Str ;
while( (q = (Str_t) strsep( (Str_t *) &p, Sep )) ){
if( s_length( q ) )
lst_add( x, q ) ;
}
return x ;
}
