 * This file specifies the format of gmon.out files.  It should have

 * number of #include's.

 *

 * A gmon.out file consists of a header (defined by gmon_hdr) followed

 * by a sequence of records.  Each record starts with a one-byte tag

 * identifying the type of records, followed by records specific data.
