+  SICS README
+
+  Requirements 
+
+  - hdf-4, hdf5- libraries: http://hdf.ncsa.uiuc.edu
+  - szlib                 : same place as HDF
+  - Mini XML library      : http://www.minixml.org/software.php
+  - libghttp              : 
+       http://ftp.gnome.org/pub/GNOME/source/libghttp/1.0/libghttp-1.0.9.tar.gz
+  - json-c                : http://oss.metaparadigm.com/json-c
+  - tcl                   : any version from 8.0, package tcl-devel on most 
+                            modern linux distros
+
+
+  Building
+
+  Install the libraries stated above, preferably to a common place.
+  Then edit the suplied makefile, instance makefile_linux, and change:
+  - uncomment all the NI, NIOBJ, NILIB stuff, except if you want support 
+    for the NI enet100 GPIB/TCP/IP converter. 
+  - Edit linux_def and set HDFROOT to where you installed your libraries
+  - Review the CFLAGS and LIBS to match your setup. Consider file format
+    format support:
+    ** HDF-4 required -DHDF4 in CFLAGS and -lmfdf -ldf in LIBS
+    ** HDF-5 support requires: -DHDF5 in CFLAGS and -lhdf5 in LIBS 
+    ** XML support requires:  -DNXXML -n CFLAGS and -lmxml in LIBS
+  - build with make -f makefile_linux
+  - Good Luck!!
+  Sorry, no configure script here. There are so few people building SICS 
+  that it is not worth the effort. The effort really is to build the 
+  libraries.
+
+
+  Running
+  
+  In the sim directory there are startup scripts for a number of different 
+  instruments. To run any of them:
+  - edit the instrument file and change the home or root variable at the 
+    top to match your setup.
+  - run with: SICServer path-to-instrument-file
+    For example: SICServer sim/topsi/morpheus.tcl
+  - Common issues:
+    ** tmp directory missing: create one
+    ** SicsDataNumber file missing: create a file with a single 0 in it
+
+  
+  Trying it out with telnet
+
+  - telnet host-where-sics-runs 2911
+  - type username and password: Spy 007 is a good idea for the supplied sims
+  - type SICS commands
+
+
+  Directories
+
+  sics             : root directory containing the SICS kernel
+  sics/psi         : psi specific drivers and stuff
+  sics/site_ansto  : ANSTO specific stuff. Currently empty, ANSTO has its 
+                     own cvs
+  sics/dummy       : example kit for defining an own site
+  sics/doc/user    : user documentation
+  sics/doc/manager : manager documentation
+  sics/doc/programmer : programmer documentation
+  sics/matrix      : matrix library used within SICS
+  sics/mcstas      : code for virtual McStas instruments
+  sics/sim         : control files for various instruments
+  sics/test        : a sort of regression test for the SICS server
+
