+Smartref package ReadMe
+
+=====================================================================
+
+This package is distributed under the terms of the LaTeX Project
+Public License
+
+=====================================================================
+
+This is the readme for the LaTeX Package ``smartref'', version 1.82
+
+The purpose of this package is to extend the capability of the
+the \ref command; precisely, whenever a label is set, this
+package records, along with the label, the values of some other
+counters (which, can be selected by the user); then, the value of
+these counters can be recalled, with a command similar to
+\pageref; moreover, this package adds a command (\s<name>ref) for
+each counter added, that displays something only if the value of
+the <name> counter is changed from when the label is set. For
+example, let's say that we are using the `amsbook' class, and we
+are numbering theorems within sections; when we want to refer to
+a theorem in another section, same chapter, we just say `as in
+theorem \ref{zorn}'; but if we want to refer to a theorem in
+another chapter, we have to set a label for that chapter and then
+say `as in theorem \ref{zorn}, in chapter \ref{chapterofzorn}';
+if we, later on, move the referenced theorem (or the referencing
+line) in some other chapter, we might need to update the
+references; with this package, there's no need for that: you say,
+at the beginning of the document:
+
+    \addtoreflist{chapter}
+
+and then, every \label is recorded alongside with the chapter in
+which it occurred. When we refer to the theorem, we might now say
+
+    theorem \ref{zorn}, chapter \chapterref{zorn}
+
+if we are sure it will always be in another chapter, or
+
+    theorem \ref{zorn}\schapterref{zorn}
+
+where the second command prints nothing if the chapter is the same
+as the current, or prints `, chap. \chapterref{zorn}' if the chapter
+has changed. Since this command sequence is supposed to be used with
+quite a frequency, it is not-so-short-handed by \srefchapterref
+(\sref<name>ref, in general).
+
+Here's a complete list of the commands made available by this
+package.
+
+\addtoreflist{<name>}
+
+This is the first command called: it says that the <name> counter
+is to be recorded alongside with all the (following) labels;
+please use it BEFORE defining any label, because the result is
+unknown if the SmartReference list changes during use (nothing
+special should happen, anyhow; it should work correctly).
+
+The previous command defines a few commands, whose name depends
+on the counter chosen. The commands are:
+
+\sget<name>val{\variable}{foo}
+
+This command gets the value of counter <name> recorded with label
+`foo', and puts this value in the chosen \variable.
+
+\<name>ref{foo}
+
+This command prints the value of the counter <name> recorded with
+label `foo'.
+
+\if<name>changed
+
+`If' construct for the next two commands:
+
+\is<name>changed{foo}
+
+Checks whether the <name> counter is changed from value recorded
+with `foo', and sets \<name>changed accordingly
+
+\s<name>ref{foo}
+
+This command prints nothing if the value of <name> is not
+different, but prints `, \short<name>name \<name>ref{foo}' if the
+value did change; the \short<name>name should be defined by the
+user. It queries by using the previous command.
+
+\sref<name>ref{foo}
+
+Equivalent of `\ref{foo}\s<name>ref{foo}'.
+
+
+The only options accepted, as for now, are `chapter' and `part';
+
+`chapter' does the following:
+
+- adds the `chapter' counter to the smart list
+
+- defines \shortchaptername to be `Cap.' if babel is loaded with
+option `italian', `Chap.' otherwise
+
+- defines \smartref to be \srefchapterref
+
+`part' does the following:
+
+- adds the `part' counter to the smart list
+
+- defines \shortpartname to be `Parte' if babel is loaded with
+option `italian', `Part' otherwise
+
+- defines \smartref to be \srefpartref if previously undefined,
+or adds \spartref to previous definition of \smartref (saved in
+\nopart@smartref) otherwise (this is mainly to be used after the
+option `chapter').
+
+As of version 1.6, the package comes with a small style file:
+
+byname.sty;
+
+it can be used alone, or within smartref, when the option
+`byname' is used; it adds the command
+
+\byname{<label>}
+
+that can be used when referencing to a section (subsection, etc) by
+name instead of number. As of version 1.8, the same style file also
+provides the command \byshortname that does the same as \byname,
+except that it uses the "short" name (the one provided in square
+brackets).
+
+Note that the references create by smartref and byname are *not*
+hyperlink, when hyperref is active. Maybe in the future ...
+
+(You can still have "named" links with hyperref using the nameref
+style file provided with hyperref itself).

+
+Heartily thanks to James Kilfiger (mapdn@csv.warwick.ac.uk) whose
+consulence has been essential (let me say vital) to the birth of
+this small package in its first revision (v0.1); it was him who
+gave me the idea to hack the \label command, and then encouraged
+me to put the newborn code in a package (and telling me how to do
+it!); it was also him that pointed out a potential bug in
+documents where chapters don't start on a page on their own
+(seems that the bug is not present, anyway ...).
+
+=====================================================================
+
+TODOs:
+
+BABEL: instead of \chaptername (for example), this package uses
+\shortchaptername, and this is not yet changed by Babel; you can
+set it up to your short form of chapter. Please send me the short
+names, so that I can implement them.
+
+Maybe put an option (`long') to make \short<name>name an alias for
+\<name>name
+
+Options: If the option is not recognized, check if it's a counter,
+and add it; otherwise, do nothing
+
+Smartrefs: check for counters that get reset by other counters
+(section in chapter, etc); maybe link to the \@addtoreset
+internal command ...
+
+ByName: refine, and add commands to do both references with a single
+command
+
+=====================================================================
+
+History:
+
+v0.1  First release (only did chapter and part).
+v1.0  First customizable release.
+v1.1  Made it work with HyperRef.
+v1.5  Added nameref.sty: reference by name.
+v1.6  Changed name to byname.sty, because of name conflict with style
+      file from the HyperRef bundle.
+v1.8  Fixed bugs in smartref, changed behaviour for unknown options,
+      fixed bug in byname that actually prevented it from functioning
+      properly.
+v1.9  Fixed limitation with AMS-LaTeX: would not handle \labels within
+      equation because AMS-LaTeX redefines the \label command for
+      equations.
+      Made \smartref robust.
