.TH t1mapper "1" "15 October 2001"
.SH NAME
t1mapper \- A tool to help xdvi use all your t1 fonts
.SH SYNOPSIS
.B t1mapper
[\fIOPTIONS\fR] \fITeX-fontdir Type1-font-file-spec\fR
.PP
.B t1mapper
[\fIOPTIONS\fR] -gs \fIGS-fontmap GS-fontdir TeX-fontdir\fR
.SH DESCRIPTION
The
.B t1mapper
comes with
.B xdvik.
It was made to make it simple to make
all sorts of Postscript<tm> Type1 (T1) fonts available to
.B xdvi.
The first invocation is to make any T1 font you may have floating around
on your system available to
.BR xdvi .
The second invocation is for hi-jacking fonts from your Ghostscript
installation, which will supply
.B xdvi
with all the standard T1 fonts it needs.
.PP
.B t1mapper
relies on a installed and working
.B texk
system to be present. In
particular it uses
.B kpsewhich
to locate the 
.B fontname
package .map files which maps between Postscript<tm> font names and TeX
font names.
.B teTeX
is one such
.B texk
system.
.PP
When invoked without the
.B -gs
option, t1mapper will examine each of the fonts specified.  It will
attempt to determine the Postscript name of the font by looking inside
the font file, and if that name has a TeX equivalent it will copy,
link or symlink your the file into the TeX font directory you named
first on the command line.  The name in the TeX font directory will be
according to the TeX/KB-fontname scheme, so that the font names used
in
.B .dvi
files matches the names found in the TeX font directories.
.PP
When invoked with the 
.B -gs
option
.B t1mapper
will read the named GS Fontmap file to determine which GS font files
correspond to which standard Postscript fonts (GS' version of
Times-Roman is not called \fITimes-Roman\fR, it's actually called
\fINimbusRomNo9L-Regu\fR), and then proceed to copy or link the files
in the named GS font directory into the named TeX font directory.
.PP
The program's diagnostic output is also written to a logfile
.IR t1map.log ,
which is created either in the current working directory or in
.BR /tmp .
.SH OPTIONS
All options except
.B -gs
have to do with how the font files are copied or linked into the TeX
font directories:
.TP
.B -cp
Copy the files from the \fIGS-fontdir\fR or matching the
\fIType1-font-file-spec\fR into the \fITeX-fontdir\fR.  This is the
default and will always work.
.TP
.B -ln
Hard link the files.  This requires the fonts to reside on the same
disk, but it will save space, and the files will not disappear from
the \fITeX-fontdir\fR if they are removed from the source directory.
.TP
.B -lns
Symlink the files.  This saves space, but if the original files are
removed the symlinks will be broken.
.TP
.B -lnlns
Attempt hard-link first, if it fails make symlink.
.TP
.B -lncp
Attempt hard-link first, if that fails, copy the font.
.SH EXAMPLES
If your Ghostscript is installed in 
.B /usr/local/share/ghostscript
and your TeX
lives in 
.B /usr/local/teTeX
then this command will make your GS fonts available to xdvi:
.PP
.Vb 4
\&t1mapper -lns -gs \e
\&	/usr/local/share/ghostscript/5.50/Fontmap \e
\&	/usr/local/share/ghostscript/fonts \e
\&	/usr/local/teTeX/share/texmf/fonts/type1/gs
.Ve
.PP
The first argument here is the full path to the GS Fontmap.  The
second is the GS font directory, note the lack of wildcards here (as
opposed to the next example).  The third argument is the TeX font
directory.  If it does not exist it will be created.  Texk and teTeX uses
quite finely structured font directories, and the above reflects this.
.PP
If you have a Solaris machine with Display Postscript fonts then this
command will make them available to xdvi:
.PP
.Vb 4
\&t1mapper -lns \e
\&	/usr/local/teTeX/share/texmf/fonts/type1/gs \e
\&	/usr/openwin/lib/X11/fonts/Type1/*.pfa
.Ve
.PP
Here the first argument is the TeX font directory and thereafter comes
a wildcard that specifies which fonts to examine for copying/linking
into the TeX font directory.
