1.1     ! root        1: Tcl
        !             2: 
        !             3: by John Ousterhout
        !             4: University of California at Berkeley
        !             5: 
        !             6: This directory contains the sources for Tcl, an embeddable tool command
        !             7: language.  For an introduction to the facilities provided by Tcl, see
        !             8: the paper ``Tcl:  An Embeddable Command Language'', in the Proceedings
        !             9: of the 1990 Winter USENIX Conference.  A copy of that paper is included
        !            10: in this directory in Postcript form:  it's in the file "usenix.ps".
        !            11: 
        !            12: This file assumes that you have received a Tcl distribution and are going
        !            13: to use Tcl on a UNIX system;  if you're running under Sprite at Berkeley,
        !            14: then some of the notes here may be incorrect.
        !            15: 
        !            16: The documentation for Tcl is present in this directory as a set of
        !            17: files with ".man" extensions.  The file "Tcl.man" gives an overall
        !            18: description of the Tcl language and facilities, and the other ".man
        !            19: files describe the library procedures that Tcl provides for tools to use.
        !            20: Read the "Tcl" man page first.  To print any of the man pages, use a
        !            21: command like
        !            22: 
        !            23:                ditroff <file>
        !            24: 
        !            25: where <page> is the name of the man page you'd like to print.  Don't
        !            26: specifiy any macros.
        !            27: 
        !            28: Type "make" to generate the Tcl library, and type "make tclTest" to
        !            29: create a simple test program that you can use to try out the Tcl facilities.
        !            30: TclTest is just a main-program sandwich around the Tcl library.  It reads
        !            31: standard input until it reaches the end of a line where parentheses and
        !            32: backslashes are balanced, then sends everything it's read to the Tcl
        !            33: interpreter.  When the Tcl interpreter returns, tclTest prints the return
        !            34: value or error message.  TclTest defines a few other additional commands
        !            35: most notably:
        !            36: 
        !            37:                echo arg arg ...
        !            38: 
        !            39: The "echo" command prints its arguments on standard output, separated by
        !            40: spaces.
        !            41: 
        !            42: There is a test suite for Tcl in the subdirectory "tests".  Read the
        !            43: README file in that directory for more information on how to use it.
        !            44: 
        !            45: The file "changes" describes recent changes that have been made to Tcl.
        !            46: If this isn't your first Tcl release, you should probably look through
        !            47: "changes" to see what's changed.  If the major release number has changed,
        !            48: i.e. from 2.x to 3.x, it means that there have been changes that aren't
        !            49: backward-compatible.
        !            50: 
        !            51: I can't promise to provide a lot of help to people trying to use Tcl, but
        !            52: I am interested in hearing about bugs or suggestions for improvements.
        !            53: Send them to me at "[email protected]".
