The package Pep2Pnk.tgz includes the modules to:
  - import PEP files into the PNK
  - export PNK nets into PEP files.

It contains following files:
  ST_Spec_LLPep.py
  HL_Spec_MNet.py
  simulateLLPep.py
  ParsePep.py
  ParseHLPep.py
  importPep.py
  importHLPep.py
  exportPep.py
  exportHLPep.py
  WritePep.py
  LLPep.py
  HLPep.py
  Readme.txt

There are also some PEP and PNK nets in the sub directory Samples.
 
The modules are written by Mike Wernicke (wernicke@informatik.hu-berlin.de). 
There is a documentation (in german) of the modules under
   http://www.informatik.hu-berlin.de/top/pnk/literatur.html

Installation:
 Please install python and the PNK (version 2.0.3 or higher) first.
 You will find further informations about the PNK under
   http://www.informatik.hu-berlin.de/top/pnk

 Copy the file Pep2Pnk.tgz in a directory of your choice 
 (e.g. ~/PNK/Application/PEP) and uncompress it by the command: 
	tar xzvf Pep2Pnk.tgz.
 
 If you want to use these Modules from everywhere you have to add this directory
 to your PATH and PYTHONPATH environment variables.
 
 Add a symbolic link of the excecutable python to /usr/local/bin/python .

Applications:
 There are two window based applications called LLPep and HLPep.
 These applications use the PNK editor for displaying the actual PNK net.

 The application LLPep is for imports and exports of low level nets.
 Usage of LLPep:
  LLPep.py [specification] or
  python LLPep.py [specification] 
   where
    specification - declares the used PNK specification,
                    default is the specification ST_Spec_LLPep from this package.

 The application HLPepFor is for imports and exports of high level nets.
 Usage of HLPep:
  HLPep.py [specification] or
  python HLPep.py [specification] 
   where
    specification - declares the used PNK specification,
                    default is the specification HLG_MNet_Specification from 
                    this package.

 There are four applications running without any user interaction, they may be 
 used in shell scripts. 
 Warning: Any graphical information will be lost in the new files using these 
          applications !

Interface:
 There are some interface functions for programers who want to use
 these modules in their own programs.

 To parse a PEP low level file you can use the module ParsePep.py.
 Import the module to your Python code by
   import ParsePep 
 and where you want to read the file call
   pep_net = ParsePep.ParseLLPep (pep_filename)
     where 
      pep_filename - is the name of the file (including the path) of the PEP net
                     to parse into pep_net.

 To parse a PEP high level file you can use the module ParseHLPep.py.
 Import the module to your Python code by
   import ParseHLPep 
 and where you want to read the file call
   pep_net = ParseHLPep.ParseHLPep (pep_filename)
     where 
      pep_filename - is the name of the file (including the path) of the PEP net
                     to parse into pep_net.
 If you want to use the created object pep_net you will to have a deeper look at
 the module and the classes defined in.

 To import a PEP low level net into a PNK net you can use the module 
 importPep.py. To import a PEP high level net into a PNK net you can use the 
 module importHLPep.py.

 Import the module to your Python code by
   import importPep or
   import importHLPep (for importing a high level net)
 and import the net with
   importPep.import_pep_ST(net, filename) or
   importHLPep.import_pep_HL(net, filename) 
     where
      net       - is the PNK net to fill,
                  there is no test wether the net is empty
      filename 	- is the name of the file (including the path) of the PEP net 
                  to import from

 To export a PNK low level net into a PEP net you can use the module 
 exportPep.py. To export a PNK high level net into a PEP net you can use the 
 module exportHLPep.py.

 Import the module to your Python code by
   import exportPep or
   import exportHLPep (for exporting an high level net)
 and export the net with
   exportPep.export_pep_ST(net, filename)
   exportHLPep.export_pep_HL(net, filename)
    where
     net 	- is the PNK net to export from,
     filename 	- is the name of the file (including the path) of the PEP net
                  which is to create, 
                  an existing one will be overwritten.
