;* The environment string "owner" points to a complete path name of a
;* file that contains the name of the owner of the copyright as the first
;* line.  Lines following the owner's name are displayed after the
;* copyright name.  This data is usually the address of the owner.
;*
;* Two different prologues are created:
;*                C file prologues
;*                Assembler/Brief macros
;* These formats differ only in the comment character.
;*
;* The header macros should be called whenever a new file is editted.
;* This is done bye inserting a (header) call in "startup.m" for each
;* file type desired.
;*
;* A prologue is created whenever the third character on the first line
;* is not a "*".  The header may be aborted by typeing escape at
;* the description prompt.
;*
;* Several other useful macros are included:
;*    c_comment   - Generate an empty comment in column 49 for C
;*    asm_comment - Generate an empty comment in column 49 for ASM
;*  comment     - Call c_comment or asm_comment depending upon
;*                  extension (usually attached to a key)
;*    function_header - Insert a functin header
