Compiler Construction in UNIX

[Bill Roberts]

Recently someone sent me mail telling of a book which discusses Lex and Yacc 
extensively.  Unfortunately, I deleted that posting after reading it only to 
find that I might really be able to use the book.  I believe the title is
"Compiler Construction in UNIX" but I do not know the author(s) or publisher.
If anyone in netland knows I would appreciate your help.  Thanks in advance.
