.SH NAME
pscat \- convert C/A/T files to PostScript language format
.SH SYNOPSIS
.B pscat
[
.BI -F fonttable
] [
.BI -i prologuefile
] [
.BI -l paperlength
] [
.BI -x xoffset
] [
.BI -y yoffset

]
.SH DESCRIPTION
.I pscat
converts C/A/T format
.IR file 
(i.e., as produced by the original
[o]troff (1)),
to \*(PS language format on the standard output.  If no
.I file
argument is given, the standard input is used.
The average user will probably be happy using 
ptroff (1),
but explicit use of 
.I pscat
gives more control.
.sp
Page offset distances and the page length 
are specified by giving a fixed-point real number optionally 
followed by a units measure.  For example, 1in means one inch, 15mm means 
fifteen millimeters.  If no units are indicated, points (72 to the inch) 
are used.
The options are:
.TP
.BI -F fonttable
specifies a font correspondence table for use by the converter.
(The default is usually
Times.ct
where the mounted fonts are:
.BR R =Times-Roman, 
.BR I =Times-Italic, 
.BR B =Times-Bold, 
and
.BR S =Symbol.
Note that 
troff
should be invoked with an appropriate 
.B -F 
switch and explicit ".fp"
commands.)
.TP
.BI -i prologuefile
specifies a file to be incorporated as the \*(PS language prologue, otherwise
the default prologue will be used (see below).
.TP
.BI -l pagelength
specifies the page length to use when splitting the
C/A/T file into pages.  The default is 11 inches.
Units are described above.
.TP
.BI -x xoffset
moves the output 
.I xoffset
to the right on the paper.  The default is 0.
Units are described above.
.TP
.BI -y yoffset
moves the output
.I yoffset
downward on the paper.  The default is 0.  Different versions of 
troff
have different notions of where 
the top edge of the paper really is, so careful setting of the 
.B -y 
switch may be necessary.
Units are described above.
.SH ENVIRONMENT
.TP
PSLIBDIR
path name of a directory to use instead of
XPSLIBDIRX for 
.I pscat
prologue and font metric files
.SH FILES
.TP 2.2i
XTROFFFONTDIRX/*.ct
character correspondence tables (built by 
pscatmap (8))
mapping C/A/T codes to \*(PS language fonts and characters or other actions
.TP
XPSLIBDIRX/pscat.pro
default \*(PS language prologue

.SH BUGS
Because of the character mapping tables used, arbitrary
use of the ".fp" troff directive will usually produce the
wrong results.  The 
family.head
files that
ptroff
feeds to 
troff
contain ".fp" commands appropriate for a given font family.
Users must build and reference correct tables with
pscatmap (8)
for non-standard ".fp" combinations to work.

The mapping from the default troff fonts to 
Adobe's Times-Roman will not look good.  \*(PS language font width 
tables (and ".fp" commands) should be used explicitly in troff.

.I pscat
determines where page breaks occur by assuming that each page is exactly
the specified length.  There is no indication of page boundaries
in the C/A/T file, so improper use of the 
.B -l 
option will lead to undesirable results.  Some 
troff 
macro packages 
generate cutmarks at logical edges of the page which may or
may not get imaged on a \*(PS printer.
Careful use of the 
.B -x 
and 
.B -y 
options may help.
