-# ngspice-klu build script for Linux, release or debug version, 64 bit
-# compile_linux_klu.sh <d>
-# https://ieeexplore.ieee.org/document/6226278
-
-# Procedure:
-# Install gcc, bison, flex, libtool, autoconf, automake, 
-# libx11 and libx11-dev (headers), libXaw and libXaw-dev, libreadline and dev
-# xmu, xet, xt, libxft, libxrender, libfreetype, libfontconfig
-# for details please see the ngspice manual, chapt. 32.1.
-# Declare 'compile_linux_klu.sh' executable and start compiling with
-# './compile_linux_klu.sh' or './compile_linux_klu.sh d' from the ngspice directory.
-# Options:
-# XSPICE (--enable-xspice) may be selected at will.
-# --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.
-# OSDI (--enable-osdi) is not yet supported by KLU
-
-# ngspice as shared library:
-# Replace --with-x by --with-ngshared in line ../configure ... .
-# Add (optionally) --enable-relpath to avoid absolute paths when searching for code models.
-# It might be necessary to uncomment and run ./autogen.sh .
