+% url.sty ver 1.2 19-Oct-1996 Donald Arseneau asnd@triumf.ca
+%
+% A form of \verb that allows linebreaks at certain characters or
+% combinations of characters, accepts reconfiguration, and can usually
+% be used in the argument to another command. It is intended for email
+% addresses, hypertext links, directories/paths, etc., which normally
+% have no spaces. The font may be selected using the \urlstyle command,
+% and new url-like commands can be defined using \urldef.
+%
+% Usage: Conditions:
+% \url{ } If the argument contains any "%", "#", or "^^", or ends with
+% "\", it can't be used in the argument to another command.
+% The argument must not contain unbalanced braces.
+% \url| | ...where "|" is any character not used in the argument and not
+% "{". The same restrictions as above except that the argument
+% may contain unbalanced braces.
+% \xyz for "\xyz" a defined-url; this can be used anywhere, no matter
+% what characters it contains.
+%
+% See further instructions after "\endinput"

+% url.sty ver 1.2 19-Oct-1996 Donald Arseneau asnd@reg.triumf.ca
+%
+% This package defines "\url", a form of "\verb" that allows linebreaks,
+% and can often be used in the argument to another command. It can be
+% configured to print in different formats, and is particularly useful for
+% hypertext links, email addresses, directories/paths, etc. The font may
+% be selected using the "\urlstyle" command and pre-defined text can be
+% stored with the "\urldef" command. New url-like commands can be defined,
+% and a "\path" command is provided this way.
+%
+% Usage: Conditions:
+% \url{ } If the argument contains any "%", "#", or "^^", or ends with
+% "\", it can't be used in the argument to another command.
+% The argument must not contain unbalanced braces.
+% \url| | ...where "|" is any character not used in the argument and not
+% "{". The same restrictions as above except that the argument
+% may contain unbalanced braces.
+% \xyz for "\xyz" a defined-url; this can be used anywhere, no matter
+% what characters it contains.
+%
+% The "\url" command is fragile, and its argument is likely to be very
+% fragile, but a defined-url is robust.
+%
+% Package Option: obeyspaces
+% Ordinarily, all spaces are ignored in the url-text. The "[obeyspaces]"
+% option allows spaces, but may introduce spurious spaces when a url
+% containing "\" characters is given in the argument to another command.
+% So if you need to obey spaces you can say "\usepackage[obeyspaces]{url}",
+% and if you need both spaces and backslashes, use a `defined-url' for
+% anything with "\".
+%
+% Package Option: hyphens
+% Ordinarily, breaks are not allowed after "-" characters because this
+% leads to confusion. (Is the "-" part of the address or just a hyphen?)
+% The package option "[hyphens]" allows breaks after explicit hyphen
+% characters. The "\url" command will *never ever* hyphenate words.
+%
+% Package Option: spaces
+% Likewise, breaks are not usually allowed after spaces under the
+% "[obeyspaces]" option, but giving the options "[obeyspaces,spaces]"
+% will allow breaks at those spaces.
+%
+% Package Option: T1
+% This signifies that you will be using T1-encoded fonts which contain
+% some characters missing from most older (OT1) encoded TeX fonts. This
+% changes the default definition for "\urlstyle{rm}".
+%
+% Defining a defined-url:
+% Take for example the email address "myself%node@gateway.net" which could
+% not be given (using "\url" or "\verb") in a caption or parbox due to the
+% percent sign. This address can be predefined with
+% \urldef{\myself}\url{myself%node@gateway.net} or
+% \urldef{\myself}\url|myself%node@gateway.net|
+% and then you may use "\myself" instead of "\url{myself%node@gateway.net}"
+% in an argument, and even in a moving argument like a caption because a
+% defined-url is robust.
+%
+% Style:
+% You can switch the style of printing using "\urlstyle{tt}", where "tt"
+% can be any defined style. The pre-defined styles are "tt", "rm", "sf",
+% and "same" which all allow the same linebreaks but different fonts --
+% the first three select a specific font and the "same" style uses the
+% current text font. You can define your own styles with different fonts
+% and/or line-breaking by following the explanations below. The "\url"
+% command follows whatever the currently-set style dictates.
+%
+% Alternate commands:
+% It may be desireable to have different things treated differently, each
+% in a predefined style; e.g., if you want directory paths to always be
+% in tt and email addresses to be rm, then you would define new url-like
+% commands as follows:
+%
+% \newcommand\email{\begingroup \urlstyle{rm}\Url}
+% \newcommand\directory{\begingroup \urlstyle{tt}\Url}
+%
+% You must follow this format closely, and NOTE that the final command is
+% "\Url", not "\url". In fact, the "\directory" example is exactly the
+% "\path" definition which is pre-defined in the package. If you look
+% above, you will see that "\url" is defined with
+% \newcommand\url{\begingroup \Url}
+% I.e., using whatever url-style has been selected.
+%
+% You can make a defined-url for these other styles, using the usual
+% "\urldef" command as in this example:
+%
+% \urldef{\myself}{\email}{myself%node.domain@gateway.net}
+%
+% which makes "\myself" act like "\email{myself%node.domain@gateway.net}",
+% if the "\email" command is defined as above. The "\myself" command
+% would then be robust.
+%
+% Defining styles:
+% Before describing how to customize the printing style, it is best to
+% mention something about the unusual implementation of "\url". Although
+% the material is textual in nature, and the font specification required
+% is a text-font command, the text is actually typeset in *math* mode.
+% This allows the context-sensitive linebreaking, but also accounts for
+% the default behavior of ignoring spaces. Now on to defining styles.
+%
+% To change the font or the list of characters that allow linebreaks, you
+% could redefine the commands "\UrlFont", "\UrlBreaks", "\UrlSpecials" etc.
+% directly in the document, but it is better to define a new `url-style'
+% (following the example of "\url@ttstyle" and "\url@rmstyle") which defines
+% all of "\UrlBigbreaks", "\UrlNoBreaks", "\UrlBreaks", "\UrlSpecials", and
+% "\UrlFont".
+%
+% Changing font:
+% The "\UrlFont" command selects the font. The definition of "\UrlFont"
+% done by the pre-defined styles varies to cope with a variety of LaTeX
+% font selection schemes, but it could be as simple as "\def\UrlFont{\tt}".
+% Depending on the font selected, some characters may need to be defined
+% in the "\UrlSpecials" list because many fonts don't contain all the
+% standard input characters.
+%
+% Changing linebreaks:
+% The list of characters that allow line-breaks is given by "\UrlBreaks"
+% and "\UrlBigBreaks", which have the format "\do\c" for character "c".
+% The differences are that `BigBreaks' have a lower penalty and have
+% different breakpoints when in sequence (as in "http://"): `BigBreaks'
+% are treated as mathrels while `Breaks' are mathbins (see The TeXbook,
+% p.170). In particular, a series of `BigBreak' characters will break at
+% the end and only at the end; a series of `Break' characters will break
+% after the first and after every following *pair*; there will be no
+% break after a `Break' character if a `BigBreak' follows. In the case
+% of "http://" it doesn't matter whether ":" is a `Break' or `BigBreak' --
+% the breaks are the same in either case; but for DECnet nodes with "::"
+% it is important to prevent breaks *between* the colons, and that is why
+% colons are `BigBreaks'.
+%
+% It is possible for characters to prevent breaks after the next following
+% character (I use this for parentheses). Specify these in "\UrlNoBreaks".
+%
+% You can do arbitrarily complex things with characters by making them
+% active in math mode (mathcode hex-8000) and specifying the definition(s)
+% in "\UrlSpecials". This is used in the rm and sf styles for OT1 font
+% encoding to handle several characters that are not present in those
+% computer-modern style fonts. See the definition of "\Url@do", which
+% is used by both "\url@rmstyle" and "\url@sfstyle"; it handles missing
+% characters via "\UrlSpecials". The nominal format for setting each
+% special character "c" is: "\do\c{<definition>}", but you can include
+% other definitions too.
+%
+%
+% If all this sounds confusing ... well, it is! But I hope you won't need
+% to redefine breakpoints -- the default assignments seem to work well for
+% a wide variety of applications. If you do need to make changes, you can
+% test for breakpoints using regular math mode and the characters "+=(a".
+%
+% Yet more flexibility:
+% You can also customize the verbatim text by defining "\UrlRight" and/or
+% "\UrlLeft", e.g., for ISO formatting of urls surrounded by "< >", define
+%
+% \renewcommand\url{\begingroup \def\UrlLeft{<url: }\def\UrlRight{>}%
+% \urlstyle{tt}\Url}
+%
+% The meanings of "\UrlLeft" and "\UrlRight" are *not* reproduced verbatim.
+% This lets you use formatting commands there, but you must be careful not
+% to use TeX's special characters ("\^_%~#$&{}" etc.) improperly.
+% You can also define "\UrlLeft" to reprocess the verbatim text, but the
+% format of the definition is special:
+%
+% \def\UrlLeft#1\UrlRight{ ... do things with #1 ... }
+%
+% Yes, that is "#1" followed by "\UrlRight" then the definition. For
+% example, to put a hyperTeX hypertext link in the DVI file:
+%
+% \def\UrlLeft#1\UrlRight{\special{html:<a href="#1">}#1\special{html:</a>}}
