+\subsubsection{Configuring conversion tables and keyboard bindings}
+%\label{subsub:gens}
+
+The 8bit package comes along with several perl%
+\footnote{the scripts are written in perl4. In order to run them with later
+  versions of perl, you have to patch the scripts in some places since perl4
+  and later versions differ in the way they expand backslashes.} scripts that
+allow you to configure the package for your own needs in a convenient way.
+
+Keyboard bindings and the major behaviour of the converter \bt{isa2latex} are
+controlled by the two configuration files \bt{key-table.inp} and
+\bt{conv-tables.inp} which reside in the directory \bt{\$ISABELLE8BIT/config}.
+As these files contain a lot of comments, their formats are rather 
+self explanatory.
+
+To change the conversions performed by \bt{isa2latex}, you just
+have to alter the file \bt{conv-tables.inp}. This file mainly contains the
+conversion tables for single characters in the code ranges 32 -- 127 and
+(usually) 161 -- 255.  The last part of the configuration file describes how the
+lexical analyser of the converter \bt{isa2latex} treats special character
+sequences. It is most likely that you change this part of the configuration
+file. 
+In order to activate your changes, you have to run the Makefile with \bt{gmake}.
+This invokes the perl script \bt{gen-isa2latex} with \bt{conv-tables.inp} as
+an argument. See the man page on \bt{gen-isa2latex} for more details about
+command line arguments. According to the configuration file, the perl script
+patches specific portions of the C source of the 
+converter in the directory \bt{\$ISABELLE8BIT/c-sources/isa2latex} and
+calls the C compiler to generate a new binary for \bt{isa2latex}.
+
+If you want to alter the keyboard bindings for the various editors and the
+terminal, you have to change the configuration file \bt{key-table.inp}. 
+The file contains as its main part a table relating keystrokes to the 
+keyboard codes to be generated. Then run the Makefile with \bt{gmake}.
+For every editor that the 8bit package supports, \bt{gmake} starts a perl script
+that patches the start up file for the specific editor. For example, for the 
+\bt{vim} editor the script \bt{gen-isavim} is started, which patches the shell 
+script
+\bt{\$ISABELLE8BIT/vim/isavim}.  As the last action, the perl script
+\bt{gen-isadoc} is invoked which generates some \bt{.dvi} files for reference
+cards which document the new keyboard mapping.
