-Installation instructions for PL/Tcl
-
-1.  Build the pltcl shared library
-
-    The Makefile for the pltcl shared library assumes the sources
-    for PostgreSQL are in /usr/local/src/postgresql-6.2.1/src. Edit
-    if not.
-
-    The Makefile depends on the tclConfig.sh file that get's installed
-    with Tcl. This should either be in /usr/lib or in /usr/local/lib.
-    If it is in a different place, edit mkMakefile.tcldefs or make a
-    symbolic link to it here.
-
-    Type make and the shared library should get built.
-
-2.  Now create the PL/Tcl language in PostgreSQL
-
-    Since the pg_language system catalog is private to each database,
-    the new language can be created only for individual databases,
-    or in the template1 database. In the latter case, it is
-    automatically available in all newly created databases.
-
-    The commands to create the new language are:
-
-        create function pltcl_call_handler () returns opaque
-    		as 'path-to-pltcl-shared-lib'
-    		language 'C';
-
-	create trusted procedural language 'pltcl'
-		handler pltcl_call_handler
-		lancompiler 'PL/Tcl';
-
-    The trusted keyword on create procedural language tells PostgreSQL,
-    that all users (not only those with superuser privilege) are
-    permitted to create functions with LANGUAGE 'pltcl'. This is
-    absolutely safe, because there is nothing a normal user can do
-    with PL/Tcl, to get around access restrictions he/she has.
-
-3.  Use PL/Tcl
-
-    Read pltcl_guide.txt to learn how to write functions and
-    trigger procedures in PL/Tcl.
