hdr -- print a file's header (the first n lines)  (EXTERNAL)

syntax:  hdr <pathname> [-Ln]

ex:      hdr thatfile
         hdr %help/= -L2

Displays lines from the beginning of a file.  Wildcards are 
allowed.  If -L is given, the specified number of lines is 
displayed.  If -L is omitted, the first 5 lines are 
displayed.

'hdr' works for AWP files and for any file type that contains
plain text (for example, txt or src).
