Debug Options
=============

  The `-d' flag to dvips is very useful for helping to track down
certain errors.  The parameter to this flag is an integer that tells
what errors are currently being tracked.  To track a certain class of
debug messages, simply provide the appropriate number given below; if
you wish to track multiple classes, sum the numbers of the classes you
wish to track.  To track all classes, you can use `-1' (output is
extremely voluminous).  Another useful value is `3650', which tracks
everything having to do with file searching and opening.

  The classes are:

1
     specials

2
     paths

4
     fonts

8
     pages

16
     headers

32
     font compression

64
     files

128
     memory

256
     Kpathsea `stat' calls

512
     Kpathsea hash table lookups

1024
     Kpathsea path element expansion

2048
