B.5. Additional standard files 393
shortvrb (Section 4.9.1) provides the commands \MakeShortVerb and
\DeleteShortVerb, to designate (and remove) a certain character
as the equivalent of \verb for printing literal text. The character,
preceded by a backslash, is given as an argument to these commands.
After \MakeShortVerb{\|} has been issued, |\cmd{x}| is
equivalent to \verb|\cmd{x}|, producing \cmd{x};
syntonly provides the command \syntaxonly which, when given in the
preamble, suppresses all output to the .dvi file, but continues to
issue errors and warnings; the job runs about four times faster than
normal; this is used to check the processing when output is not
immediately needed;
t1enc makes the T1 font encoding (Section G.4.3) the standard, for use
with DC or EC fonts;
textcomp makes the special symbols in the text companion fonts available
in text mode (Section G.4.4);
tracefnt is a diagnostic tool for checking NFSS font selections; the
options given with \usepackage control its action:
errorshow suppresses all warnings and information messages to
the monitor, which are still sent to the transcript file; only error
messages are printed to the monitor;
warningshow prints warnings and error messages on the monitor;
this behavior is much the same as when the package is not used
at all;
infoshow (default option) sends font selection information to the
monitor, which is normally only written to the transcript file;
debugshow writes considerably more information to the transcript
file about every change of font; can produce a very large transcript;
pausing turns all warnings into error messages so that processing
temporarily stops, awaiting user response;
loading shows the loading of external fonts.
B.5.4 The tools packages
The members of the L AT E X3 Team, as individuals, have written a number
of packages that they collectively make available; these are to be found in
the texmf\tex\latex\tools\ directory. Although contributions, they
are considered to be part of the standard installation.
Many of these have been described elsewhere in this book, but we list
them all here.
