+Welcome to tclspice README_tcl
+
+This files acompanies ngspice sources starting with ngspice-rework-18. It 
+describes what tclspice is, its installation, and points to resources that will
+help you to start with it. It also contains usefull datas to keep informed,
+get help, or get involved in the project.
+
+Enjoy
+
+Lionel (saintel@users.sourceforge.net)
+
+
+
+What is tclspice:
+
+tclspice is a variant of ngspice. It share 95% of its code (approx). The 
+different between plain NGspice and tclspice is the type of binary it produces, 
+and the way to access it. NGspice is a standalone program that you can execute 
+and which can either automatically process a spice directives script. It can 
+also propose you a command line interface.
+tclspice is a tcl package name. It is based on libspice shared library. This 
+library is specifically designed to be loaded in tcl interpreters such as tclsh 
+or wish. Then all spice directives are available as tcl functions. libspice also
+feature some new commands that are usefull for the integration into the tcl 
+environment. 
+
+tclspice differs from ngspice by its printf (bundled to tcl printf), malloc (tcl
+ malloc), data handling and plotting (BLT toolkit extensions to tcl/tk).
+
+
+Installing:
+
+Tclspice relies on three packages that are not included in ngspice:
+tcl : the tcl command interpreter, for interpretion of user scipt
+tk  : the graphical extension of tcl, to represent data graphically and for GUIs
+blt : BLT toolkit gives number handling and plotting features to tcl/tk
+
+The most tested configuration is the latest:
+tclspice-18
+tcl 8.4
+tk 8.4
+blt 2.4
+
+Tclspice is built and installed the same way as ngspice. Then, after reading this 
+paragraph, the information you lack will probably be in README file in this directory.
+There is a configuration flag to set in order to compile tclspice library rather than
+plain ngspice, that is a standalone program. This flag is --with-tcl. It accepts an
+argument the path to tclConfig.sh
+
+If you don't provide any argument, configure script will try to find it automatically.
+  ./configure --enable-xspice --disable-cider --disable-xgraph --enable-numparam --with-readline=no --enable-adms=non --with-tcl
+
+If its does not, then it will propose you some possible locations.
+  can't find Tcl configuration script "tclConfig.sh"
+  Should you add --with-tcl=/usr/lib/tcl8.4/tclConfig.sh to ./configure arguments?
+
+If it does not, check that tcl8.4 is installed, and manually specify the path.
+  ./configure --enable-xspice --disable-cider --disable-xgraph --enable-numparam --with-readline=no --enable-adms=non --with-tcl=/usr/lib/tcl8.4
+
+Tclspice is not compatible with ngspice graphical code. Then when building tclspice,
+--no-x is automatically configured.
+
+
+
+Support and help :
+
+First of all (but last recourse), mail me at saintel@users.sourceforge.net
+
+For any kind of information on tclspice:
+  http://ngspice.sourceforge.net/tclspice.html
+It gives plenty of information. There is an index of good resources that you can
+read to get into tclspice quickly and proficently.
