+%%%%
+%%%%  This package has the LPPL maintenance status `maintained' and is
+%%%%  currently maintained by MSP:  contact@mathscipub.org 
+%%%%
+%%%%  It comprises two files: pinlabel.sty (this file) and the manual
+%%%%  pinlabdoc.pdf where full documentation may be found.
+%%%% 
+%%%% 
+%%%%  pinlabel.sty  is designed for inserting perfectly formatted TeX
+%%%%       labels in eps or pdf files for inclusion in documents.
+%%%%       It uses the coordinates provided by ghostview (or gv) to
+%%%%       position the label and reads the relevant bounding box
+%%%%       information from the eps file (which must be provided: if
+%%%%       your figure exists only as a pdf file, then run pdf2eps).
+%%%%       Several features are provided which facilitate perfect 
+%%%%       first-time label positioning, of which the most important
+%%%%       is auto-spacing, which sets the label a predetermined gap
+%%%%       away from the figure object which is being labelled.  The
+%%%%       gap is \hair (a TeX dimension, preset to 3pt, but settable
+%%%%       on the fly) and the direction of the spacing is chosen 
+%%%%       automatically.  The result is consistent and eye-pleasing
+%%%%       spacing.
+%%%%       In use, read the position of the object that you wish to
+%%%%       label and do not guess the position of the actual label.
+%%%%       Then choose the orientation of the label (eg [tr] which
+%%%%       means top-right) and the label will automatically be set
+%%%%       so that top-right of the label bounding box is set one  
+%%%%       \hair away from the object being labelled.
+%%%%       
+%%%%       
+%%%%  pinlabel.sty  was written specifically for the use of editors and  
+%%%%       authors of MSP papers and is the recommended package for
+%%%%       use for labelling diagrams for MSP.
+%%%%        
+%%%%  pinlabel.sty  is a revised version of geomsfig.sty with improved 
+%%%%       functionality and simpler syntax.  The old syntax remains
+%%%%       available for backwards compatibility, see below.
+%%%% 
+%%%%  new syntax: \pinlabel {label} by x-pin y-pin at x-location y-location
+%%%%       and   \pinlabel* {label} by x-pin y-pin at x-location y-location
+%%%% 
+%%%%       where "x-pin y-pin" is the point in intrinsic coords in label
+%%%%       space where we are placing the pin and "x-location y-location" 
+%%%%       is the point in diagram space (in PS points as read in gv) where
+%%%%       the label is pinned.  \pinlabel uses \hair autospacing \pinlabel*
+%%%%       does not.  See the manual for full details. 
+%%%%       \mathsurround is set to 0pt for parsing the label
+%%%% 
+%%%%  options:  "by x-pin y-pin" may be omitted the default is 0 0
+%%%%       orientation commands [r], [l] etc may replace "by x-pin y-pin"
+%%%%                            [r] is right-centre (same as "by 0 1") etc
+%%%%       a manual adjustment "<x-adj, y-adj>" may be added before "at"
+%%%%       or directly after the label
+%%%%          
+%%%%  Examples  \pinlabel $a^b$ [l] <-2pt,1pt> at 231 47 
+%%%%  Same as   \pinlabel $a^b$ by -1 0  <-2pt,1pt> at 231 47 
+%%%%  Same as   \pinlabel $a^b$ <-2pt,1pt> [l] at 231 47 
+%%%%  Same as   \pinlabel $a^b$ <-2pt,1pt> by -1 0  at 231 47 
+%%%%           
+%%%%           which pins "$a^b$" by centre-left at 231 47 with two 
+%%%%           adjustments: \hair (autospacing) and then (-2pt,1pt) manual
+%%%%
+%%%%           \pinlabel* {A nice figure} [Bl] <-5pt,0pt> at 231 47 
+%%%%           
+%%%%           which pins "A nice figure" by baseline-left at 231 47  
+%%%%           with one adjustment: (-5pt,0pt)
+%%%%
+%%%%  Full list of orientation commands:  r=right, l=left, t=top, b=bottom
+%%%%       and B=baseline,  default is centre and any sensible combination 
+%%%%       of two commands may be give (in either order) eg 
+%%%%       [tl]=[lt]=top-left of label bounding box
+%%%% 
+%%%%  NB the commands are syntax sensitive and use spaces as separators so
+%%%%       they DON'T work with \obeyspaces set.    Braces must be placed 
+%%%%       around labels containing spaces but may be omitted if there are
+%%%%       no spaces in the label code (see the examples above and below).
+%%%%
+%%%%  Label instructions go either in the file inside \labellist 
+%%%%       ... \endlabellist  or in a separate .lab file (ie if fig 
+%%%%       is fig4-1.eps or .ps, then labels go in \figdir/fig4-1.lab 
+%%%%       where \figdir/ is the directory containing fig4-1.eps).  
+%%%%       The \labellist overrides a .lab file.
+%%%%       \labellist ... \endlabellist can be given at any time before 
+%%%%       the next figure, but typically will be included in the figure 
+%%%%       code, as in the following example.
+%%%%
+%%%%  Here is a complete example of a relabelled figure:
+%%%%
+%%%%          \begin{figure}[ht!]
+%%%%          \labellist\small\hair 2.5pt
+%%%%          \pinlabel {$\partial _1 X$} by 1 0 at 156 426
+%%%%          \pinlabel {$\partial _2 X$} by -1 1 at 334 429
+%%%%          \pinlabel $X_1$ at 431 513 
+%%%%          \pinlabel $X_2$ at 428 460 
+%%%%          \pinlabel $H_X$ [lb] at 311 622
+%%%%          \pinlabel* $H_X'$ [tr] <-1.5pt,-2pt> at 178 370
+%%%%          \endlabellist
+%%%%          \centerline{\psfig{file=\figdir/decomp,width=3in}}
+%%%%          \caption{Labelling the boundary components of $X$}
+%%%%          \label{Fig:decomp}
+%%%%          \end{figure}
+%%%%
+%%%%  The actual figure can be included by using either psfig or 
+%%%%      graphicx.  psfig is used by the code, but graphicx 
+%%%%      commands are translated automatically, so in the above
+%%%%      example the alternative code:
+%%%%
+%%%%          \centerline{\includegraphics[width=3in]{\figdir/decomp}}
+%%%%          
+%%%%      would produce identical results.  Automatic translation ONLY  
+%%%%      takes place is a labellist is present, so if you use a .lab
+%%%%      file then you MUST use the psfig syntax.
+%%%%          
+%%%%          
+%%%%                            VERY IMPORTANT   
+%%%%                            ==============
+%%%%      
+%%%%      The file extension MUST NOT be given.  The program will find
+%%%%      the correct file (\figdir/decomp.eps or .ps or .pdf).
+%%%%      
+%%%%      READ THE BUGS below before using \includegraphics with pinlabel.
+%%%%      
+%%%%          
+%%%%  old syntax: \setlabel is unchanged (but \mathsurround is set to 0pt) 
+%%%%       \setlabel* is a new variant which sets \hair to 0pt (no 
+%%%%       autospacing) and an optional manual adjustment may be added
+%%%%       eg:
+%%%%
+%%%%           \setlabel<-2pt,-1pt>{a^b}{321}{33}{1}{1}
+%%%%           \setlabel*<-2pt,-1pt>{a^b}{321}{33}{1}{1}
+%%%%           \setlabel{a^b}{321}{33}{1}{1}
+%%%%           \setlabel*{a^b}{321}{33}{1}{1}
+%%%%       
+%%%%       the first uses autospacing and adds a (-2pt,-1pt) manual
+%%%%       adjustment;  the second uses just the manual adjustment,
+%%%%       the third just autospacing and the fourth nothing.
+%%%%
+%%%%       old and new syntax may be mixed in a label list and given 
+%%%%       either in a .lab file or inside \labellist ... \endlabellist
+%%%%
+%%%%    ***Users of geomsfig note the change to \mathsurround.  If you 
+%%%%       do not use it, there will be no change in label positioning.
+%%%%       If you do, labels may move a small amount horizontally.***
+%%%%
+%%%% 
+%%%% !!!NBNB label is in horizontal mode in new syntax and math mode in old!!!
+%%%% 
+%%%%
+%%%%  BUGS:  NO spaces are permitted in the file argument of \psfig
+%%%%      Autotranslation of \includegraphics[]{} means that no
+%%%%      spaces are permitted in the file argument to \includegraphics
+%%%%      Eg  \includegraphics[width=4in]{ foo } will produce errors,
+%%%%      use \includegraphics[width=4in]{foo}.  Spaces are permitted
+%%%%      with other arguments.
+%%%%          
+%%%%      Many of the options in graphicx are not supported.  The     
+%%%%      supported ones are:  width, height, scale, bbllx, bblly
+%%%%      bburx, bbury and clip.  The syntax for clip is "clip=".
+%%%%      Replace "keepaspectratio=true" by "proportional=".
+%%%%      
+%%%%      The command \reallyincludegraphics will force the use of
+%%%%      graphicx (ie cancel autotranslation).  Since code will use 
+%%%%      graphicx automatically if there is no labellist present, 
+%%%%      \reallyincludegraphics will only be needed if a labellist 
+%%%%      has already been given for a later figure.
+%%%%     
+%%%%      \graphicspath{} is not supported.  Use \figdir instead.
+%%%%              
+%%%%
+%%%%     Automatic configuration for dvips and pdflatex is included 
+%%%%     in this file.  No support is provided for other drivers.
+%%%% 
+%%%%     NB \psfig ouputs a vbox, which is not centred in latex' {center} 
+%%%%     environment.  Either use \centerline{} or type \leavevmode
+%%%%     before \psfig{..}.  The translator adds \leavevmode for 
+%%%%     \includegraphics, which therefore centres correctly as usual
+%%%%     in the {center} environment.
+%%%%
+%%%%  PLAIN TeX compatibility:  uses miniltx.tex and works with dvips 
+%%%%     but NOT with pdftex.  For pdf output from plain TeX use dvips 
+%%%%     followed by ps2pdf.
