If no .I file is mentioned, the standard input is used. The \*(PS file is sent to the standard output. The options are: .TP .BI \-F " fontdir" take font information from .I fontdir instead of the default (see below). .TP .BI \-p " prologue" use the contents of .I prologue instead of the default \*(PS prologue (see below). .TP .BI \-o " list" prints pages whose numbers are given in the comma-separated .IR list . The list contains single numbers .I N and ranges .IB N1 \- N2. A missing .I N1 means the lowest-numbered page, a missing .I N2 means the highest. .PP .B Note: the input for .I psdit should be prepared with the corresponding .B \-Tpsc option of .RI [ di ] troff , .IR pic , etc. .br .I eqn should be run with the flags .B \-r576 and .BR \-m2 to produce suitable output. .br .I pic should be run with the .B \-D flag. With .B DWB .IR pic , use .B \-T576 to set the correct resolution. .PP .I psdit allows for users to cause .I troff to include arbitrary \*(PS code in the generated \*(PS file. .I psdit recognizes the heretofore undefined ``%'' command in the ditroff intermediate file format to signal the start of raw \*(PS to be placed .I as is in the the output file. Everthing between (but not including) the percent sign and a line containing a single period (``.'') will be placed in the generated \*(PS output. This \*(PS is not insulated from the .I ditroff coordinate system or the state of the generated \*(PS. However, two functions are defined in the prologue so that user's may insulate themselves if they so desire. The .B PB function (for \fIpicture begin\fP) will perform a \*(PS .B save operation, translate the \*(PS coordinate system to .I ditroff's idea of the current position on the page, and change the scale and orienation of the coordinate system axes to be the standard \*(PS 72 units per inch. The .B PE macro (for \fIpicture end\fP) will end this protected environment. .LP Several methods may be employed to incorporated such included \*(PS into the ditroff intermediate file. The ``.cf'' ``.sy'' and ``\\\&!'' .I troff commands may be useful. For example, the following sequence may appear in \fItroff\fP input: .RS (usual troff input) .br \\\&!%PB .br \&.cf mypic.ps .br \\\&!PE .br \\\&!. .br (more regular troff input) .RE to include .I mypic.ps as an illustration. This facility is both powerful and useful, but indiscriminate inclusion of badly-behaving \*(PS code may be dangerous to your document's health. .SH ENVIRONMENT .TP PSLIBDIR path name of a directory to use instead of /usr/misc/lib/ps for psdit prologue. .SH FILES .TP 2.2i /usr/misc/lib/font/devpsc/* \fIditroff\fR default description files for \*(PS virtual device. .TP /usr/misc/lib/ps/psdit.pro default \*(PS prologue. .SH "SEE ALSO" psroff(1). .br 4.2bsd: ditroff(1), lpr(1). .br System V: troff(1), lp(1). .br \fIA Typesetter-independent TROFF\fR Brian W. Kernighan, Bell Laboratories 1982 .br .I Documenter's Workbench .SH AUTHOR Adobe Systems Incorporated .SH BUGS The versions of .I eqn and .I pic distributed with ditroff (from AT&T) have the device names compiled in (so much for device independence!). They should just read the device description file for the information they need. You must be careful to know which version of .I eqn you are running or you will get undesirable results. .br The B-splines generated by .I ditroff are drawn with an approximation. The functions .B D~ and .B D~~ in the prologue need a little work. .SH NOTES \*(PS is a trademark of Adobe Systems Incorporated. .br Documenter's Workbench is a trademark of AT&T Technologies.
