+These files comprise the basic building blocks for a Tcl Extension
+Architecture (TEA) extension.  For more information on TEA see:
+
+	http://www.tcl.tk/doc/tea/
+
+This package is part of the Tcl project at SourceForge, and latest
+sources should be available there:
+
+	http://tcl.sourceforge.net/
+
+This package is a freely available open source package.  You can do
+virtually anything you like with it, such as modifying it, redistributing
+it, and selling it either in whole or in part.
+
+CONTENTS
+========
+The following is a short description of the files you will find in
+the sample extension.
+
+README.txt	This file
+
+install-sh	Program used for copying binaries and script files
+		to their install locations.
+
+tcl.m4		Collection of Tcl autoconf macros.  Included by a package's
+		aclocal.m4 to define SC_* macros.

+#       DL_LIBS -       Library file(s) to include in tclsh and other base
+#                       applications in order for the "load" command to work.
+#       LDFLAGS -      Flags to pass to the compiler when linking object
+#                       files into an executable application binary such
+#                       as tclsh.
+#       LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
+#                       that tell the run-time dynamic linker where to look
+#                       for shared libraries such as libtcl.so.  Depends on
+#                       the variable LIB_RUNTIME_DIR in the Makefile.
+#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
+#                       of a shared library (may request position-independent
+#                       code, among other things).
+#       SHLIB_LD -      Base command to use for combining object files
+#                       into a shared library.
+#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
+#                       creating shared libraries.  This symbol typically
+#                       goes at the end of the "ld" commands that build
+#                       shared libraries. The value of the symbol is

+#                       be specified when creating a shared library.  If
+#                       dependent libraries should not be specified (as on
+#                       SunOS 4.x, where they cause the link to fail, or in
+#                       general if Tcl and Tk aren't themselves shared
+#                       libraries), then this symbol has an empty string
+#                       as its value.
+#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
+#                       extensions.  An empty string means we don't know how
+#                       to use shared libraries on this platform.
+#       TCL_LIB_FILE -  Name of the file that contains the Tcl library, such
+#                       as libtcl7.8.so or libtcl7.8.a.
+#       TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
+#                       in the shared library name, using the $VERSION variable
+#                       to put the version in the right place.  This is used
+#                       by platforms that need non-standard library names.
+#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
+#                       to have a version after the .so, and ${VERSION}.a
+#                       on AIX, since the Tcl shared library needs to have
+#                       a .a extension whereas shared objects for loadable
+#                       extensions have a .so extension.  Defaults to

+#       TCL_NEEDS_EXP_FILE -
+#                       1 means that an export file is needed to link to a
+#                       shared library.
+#       TCL_EXP_FILE -  The name of the installed export / import file which

+#                       Empty if Tcl is unshared.
