XDefault flags:
X    ba bb bs cba cbb cea ceb da dba dbb dea deb ea eb lca rcb pn ia gi
X
XWays to change flags:
X
X    Put a command line into your PostScript code...
X
X    example:
X        <beginning of line>%%= -bs +cea -dba
X
X    Put a command line into a .pspp in your home directory
X
X    example:
X        -lba -rba -lca
X
X    Set options when you call program...
X
X    example:
X        pspp -rca
X
XTo run:
X
X% pspp [options files] < file.in > file.out
X
XOr, run it from vi...
X
X:%!pspp
X
XOr,
X
X% pspp -lba foo.cps +lba foobar.ps
X
XSpecial NeWS related features...
X
X    lines beginning with cdef are assumed to be cdef calls under NeWS.
X    This causes the rest of the file (till the next cdef) to be indented one.
X
X    Lines beginning with "#" or "%" are passed through unmodified.
X
XNote to hackers:
X    You may notice how I stuck lots of the keywords together into
X    a single lex rule... I am not going to explain this... there is
X    a reason for this... don't worry about it for now.  The reason
X    doesn't show up in this version.
