1.3       millert    84: .It Fl p Ar pattern
                     85: The file is split whenever an input line matches
                     86: .Ar pattern ,
                     87: which is interpreted as an extended regular expression.

                     97: of the input file which is to be split.
                     98: If a second additional argument is specified, it is used as a prefix
                     99: for the names of the files into which the file is split.
                    100: In this case, each file into which the file is split is named by the
1.4       aaron     101: prefix followed by a lexically ordered suffix in the range of

                    106: argument is not specified, the file is split into lexically ordered
