+   fitsTcl can be built under PC Linux or Mac OS X, and requires the
+   CFITSIO and Tcl packages.  Instructions for building the software
+   are below.
 
-   fitsTcl can be built under Unix/Linux (PowerPC or Intel), MacOS,
-   and Windows.  You will need a version of Tcl8.x, available either
-   from Scriptics (www.scriptics.com) or HEASARC as part of the fv
-   distribution (heasarc.gsfc.nasa.gov/ftools/fv).  Read the following
-   for instructions for building on each platform.
+   Please send any questions or problem reports to the FTOOLS help desk:
+   
+       ftoolshelp at bigbang.gsfc.nasa.gov.
 
+   Before building fitsTcl, make sure you have Tcl installed on your
+   machine and can locate the tcl.h header file.  To build the fitsTcl
+   library:
 
+   1.  Download the latest version of the cfitsio source code from:

-********************************************************************************
+         http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html
 
+       and unpack the tar file.
 
-   To build the fitsTcl shared library do the following:
+   2.  Unpack the compressed fitsTcl tar file and enter the fitsTcl-2.4
+       directory.
 
-      1.  Unpack the compressed fitsTcl tar file and enter the fitsTcl2.1.1
-          directory.
+   3.  Configure fitsTcl for your system with the command
 
-      2.  Download the latest version of the cfitsio source code (for UNIX)
-          from:
+          ./configure [optional arguments]
 
-          http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/fitsio/fitsio.html
+       where the optional arguments are:
 
-          and unpack the source tar file.
+          --prefix=DIR1 --with-cfitsio=DIR2 --with-tcl-includes=DIR3
 
-      3.  Configure fitsTcl for your system with the command
+          DIR1 is the installation path (default is /usr/local)
 
-             ./configure [optional arguments]
+          DIR2 is the path to the cfitsio source directory
+               (default is ./cfitsio)
 
-          where the optional arguments are:
+          DIR3 is the path to the location of the tcl.h header file
+               (default is $prefix/include or /usr/include).
 
-             --prefix=DIR1 --with-cfitsio=DIR2 --with-tcl-includes=DIR3
+       These may be considered optional only if the defaults are valid
+       for your system/setup.
 
-             DIR1 is the installation path (default is /usr/local)
+       Under the Cygwin environment, an additional argument is required:
 
-             DIR2 is the path to the cfitsio source directory
-                  (default is ./cfitsio)
+          --with-tcl=DIR4
 
-             DIR3 is the path to the location of the tcl.h header file
-                  (default is $prefix/include or /usr/include).
+          DIR4 is the path to the location of the Tcl library (libtcl8.x.dll).
 
-          These may be considered optional only if the defaults are valid
-          for your system/setup.
+       The final library will be installed in the directory DIR1/lib
+       which must exist.  Note that the library itself does not depend
+       on the value of DIR1, only the installation step in the Makefile.

-   To build fitsTcl extension do the following:
-
-      1.  Download and build the Mac TCL software available from
-          Scriptics (www.scriptics.com).
-
-      2.  Download and expand the fitsTcl distribution, which will
-          create a fitsTcl2.1.1 subdirectory.
-
-      3.  Download the latest version of the cfitsio source code from:
-
-          http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/fitsio/fitsio.html
-
-          and untar it under the fitsTcl2.1.1 directory (i.e. such that
-          you have a fitsTcl2.1.1/cfitsio directory).
-
-      4.  Debinhex and expand the file fitsTcl.sit.hqx, creating
-          a fitsTcl folder containing a Codewarrior 5 project file,
-          fitsTcl.p.
-
-      5.  Open the new project file and update the Access Paths to
-          point to your TCL source tree.
-
-      6.  Build the 'fitsTcl DLL' target.  This will create a file
-          fitsTcl.dll in the fitsTcl directory.  Move it to where ever
-          is convenient and use 'load fitsTcl.dll' to load it into
-          tclsh or wish.
-
-   (Note: We do not distribute a binary version of the plugin since it
-   is dependent on the major TCL version -- 8.0, 8.1, etc -- used in
-   building it.  We may distribute one, though, if there is sufficient
-   demand for use with a particular TCL release.)

-
-
-   Building fitsTcl requires Microsoft Visual C++.  A Borland C v5
-   makefile is also included, although it has not been updated since
-   the last release.
-
-   To build fitsTcl DLL do the following:
-
-      1.  Download and build the Windows TCL software available from
-          Scriptics (www.scriptics.com).
-
-      2.  Download and expand the fitsTcl distribution, which will
-          create a fitsTcl2.1.1 subdirectory.
-
-      3.  Download the latest version of the cfitsio source code from:
-
-          http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/fitsio/fitsio.html
-
-          and untar it under the fitsTcl2.1.1 directory (i.e. such that
-          you have a fitsTcl2.1.1/cfitsio directory).
-
-      4.  Edit the file makefile.vc (or makefile.bc5) and update the
-          paths for your specific setup.  We have our source tree at
-          D:\FV_SRC.  Replace this and the TCL8.2.2 references as
-          appropriate.
-
-      5.  Type the command 'nmake -f makefile.vc'.  This will build
-          a fitstcl.dll file.  Move it to where ever is convenient and
-          use 'load fitstcl.dll' to load it into tclsh or wish.
+   You may need to specify an explicit path to the library or set the
+   LD_LIBRARY_PATH (DYLD_LIBRARY_PATH on Mac OS X) to its location.
