+Computer filenames, host names, and e-mail
+addresses tend to be long strings that
+cause line breaking problems for \TeX\@.
+Sometimes rather long strings are
+encountered, such as:
+%
+\begin{verbatim}
+  mighty-mouse-gw.scrc.symbolics.com
+\end{verbatim}
+%
+This file defines a macro, \verb+\path|...|+,
+similar to \LaTeX's \verb+\verb|...|+ macro, that
+sets the text in the typewriter font,
+allowing hyphen-less line breaks at
+punctuation characters.
+
+The default set of punctuation characters is
+defined as
+%
+\begin{verbatim}
+  \discretionaries |~!@$%^&*()_+`-=#{"}[]:;'<>,.?\/|
+\end{verbatim}
+%
+However, you can change it as needed, for
+example
+%
+\begin{verbatim}
+  \discretionaries +@%!.+
+\end{verbatim}
+%
+would assign to it the set \verb+@ % ! .+ which
+commonly occur in electronic mail addresses.
+
+The delimiter characters surrounding the
+arguments to \cmd{\discretionaries} and \cmd{\path}
+will normally be a punctuation character not
+found in the argument, and not otherwise
+significant to \TeX\@.  In particular, backslash
+cannot be used as a delimiter.  In the rare
+event that this is required, set
+%
+\begin{verbatim}
+  \specialpathdelimiterstrue
+\end{verbatim}
+%
+This practice is not recommended, because \TeX\ %
+then runs about four times slower while it is
+typesetting \verb+\path\...\+ requests.
+\cmd{\specialpathdelimitersfalse} is the normal
+setting.
+
+This file may be used in \hologo{plainTeX} or \hologo{AmSTeX}
+by
+%
+\begin{verbatim}
+  \input path.sty
+\end{verbatim}
+%
+and in \LaTeX\ by
+%
+\begin{verbatim}
+  \usepackage {path}
+\end{verbatim}
+
+The \texttt{checksum} field above, if present, contains
+a CRC-16 checksum as the first value, followed
+by the equivalent of the standard UNIX \texttt{wc} (word
+count) utility output of lines, words, and
+characters.  This is produced by Robert
+Solovay's \texttt{checksum} utility.
+
+
+\section*{The \cmd{\path} Macro}
+
+An early prototype of this code which was developed by Nelson~H.~F.
+Beebe \bmail{beebe@math.utah.edu} used a recursive macro to peel off one
+character at a time, then with a nest of \verb+\ifx+ statements, test for
+each punctuation character, and if one is found, insert discretionary
+linebreaks in the form of \cmd{\-} or \verb+\penalty0+\@.  While this usually works,
+it is not entirely satisfactory, because the nested \verb+\ifx+ statements
+are ugly, and the recursion can exhaust \TeX's macro stack for
+arguments longer than about 30~characters.
+
+A second version by NHFB built upon the ideas used by the \LaTeX\ %
+\verb+\verb|...|+ macro; this was mostly successful, but was flawed by its
+inability to handle at least the three characters \verb+^ [ ]+, by loss of
+use of \texttt{@} for naming internal private macros, and by its inability to
+allow the set of characters at which breaks are permissible.
+
+The problem was then passed off to Philip Taylor, who wrote this third
+version which fully solves the problem.  Phil therefore gets the
+author credit in the file header above.  [Gee, thanks~!  $**$ Phil]

+  Summary:   & No code changes.  An out-of-date example removed, the syntax for \LaTeXe\ changed to ``\verb+\usepackage {path}+'', and the ``checksum'' comments modified to indicate that the checksum is not necessarily present.  The initial opening brace re-positioned to align with the matching closing brace, and the inner closing brace re-positioned to align with the inner opening brace.  A check made to ensure that no \textsf{\textlangle tab\textrangle} characters are present. \\[\bigskipamount]
+  \multicolumn{2}{@{}l@{}}{3.03a [22-Jul-1997]} \\
+  Summary:   & No code changes from V3.03; e-mail addresses, telephone numbers, etc.\ amended to reflect current situation.  Checksum removed. \\[\bigskipamount]
+  \multicolumn{2}{@{}l@{}}{3.03 [03-Dec-1991]} \\
+  Problem:   & A \verb+\path|...|+ entry in a \LaTeX\ index is set with an preceding blank line. \\
+  Solution:  & Add \cmd{\leavevmode} before \verb+\hbox{}+; without it, an extra blank line gets typeset before every invocation of \cmd{\path} in a \LaTeX\ \env{theindex} environment. \\
+  Diagnosis: & To avoid hyphenation, the expansion of \cmd{\path} starts with an \verb+\hbox{}+ (c.\,f.\ the \TeX book, p.~454); \LaTeX\ indices are basically set in vertical mode, with each index entry a paragraph in its own right; when an \verb+\hbox {}+ is encountered in vmode, it is typeset in vmode, and \TeX\ continues; the first real character is encountered, and \TeX\ enters unrestricted horizontal mode.  The \verb+\hbox {}+ and the first character are therefore on separate lines, separated by \cmd{\baselineskip}. \\[\bigskipamount]
