NLUPDATE V2.20                by J”rg Spilker (2:2432/407, 90:4/0)

    Please read this document carefully.  There are some changes to former 
    versions of NLUPDATE.


    NLUPDATE is just a little tool for nodelist maintenance. NLUPDATE will 
    decompress  DIFF's  and LIST's without  difference  files,  apply  the 
    DIFF's  and  start a nodelistcompiler (like PARSELST).  If  you  will, 
    NLUPDATE compresses new nodelists and creates regional nodelists  with 
    the program PRVNODES (by Gnther Parcia).

    Please notice:  NLUPDATE won't delete any compressed LIST's and DIFF's 
    anymore  (as in former versions).  You should use MUPDATE  instead  of 
    this.

    NLUPDATE needs a configuration file named NLUPDATE.CFG.  The file  was 
    searched in the actual directory,  then in the directory to which  the 
    environment  variables MAILER or BINKLEY points.  If it is not  found, 
    then NLUPDATE will stop.

    You  could use the following keywords in the configuration file  (some 
    entries are optional (*) and only necessary in some cases):

    NListComp  : fullpath/name and options of the nodelistcompiler.

    Pn24User(*): fullpath/name and options of a userlist utility.

    PrvtNode(*): fullpath/name of PRVNODES.TOS

    ArcImp     : fullpath/name and options to unpack for ARC

    ArcExp     : fullpath/name and options to pack   for ARC

    LzhImp     : fullpath/name and options to unpack for LHarc.

    LzhExp     : fullpath/name and options to pack   for LHarc.

    ZipImp     : fullpath/name and options to unpack for ZIP.

    ZipExp     : fullpath/name and options to pack   for ZIP.

    NetFile    : directory where the DIFF's arrive (normally the inbound).

    NodeList   : nodelist directory.

    StatusLog  : logfile for NLUPDATE.

    NewList(*) : directory  where NLUPDATE creates new LIST's.  You  could 
                 move  these LIST's into the appropriate directories  with 
                 TIC's AUTOSEND option.

    Please notice that the existence of the path's is not checked and that 
    the keywords are case-sensitive.


    How  do i tell NLUPDATE which DIFF's and LIST's to handle.  There  are 
    three possibilities.


    1) uncompressed lists:

    Copy filename,{filename}..

    If  NLUPDATE finds one of the filenames in the NetFile  directory,  it 
    will be copied to the NodeList directory.

    Example:

    Copy 25502.upd,network.245

    Note: The nodelistcompiler won't be started.


    2)  Compressed  LIST's (with and without  DIFF's).  These  LIST's  are 
    defined by the keyword LisI (where I is a number between 1-5).

    LisI [N|A|L|Z][N|A|L|Z] listname,diffname {option}

    or 

    LisI [N|A|L|Z] listname {option}

    Meaning of the flags:

    The  first flag is for creating new compressed LIST's  after  applying 
    the DIFF.  With the second flag,  a difference file could be converted 
    into  a  new format.  The lists are created in the  NewList  directory 
    (which you should have defined in the config).

    N: Don't compress new LIST's/DIFF's.

    A: Pack with ARC.

    L: Pack with LHarc.

    Z: Pack with ZIP.
    
    If  an option is specified,  the nodelistcompiler will be  invoked 
    with these option.

    Example:

    Lis1 ZL nodelist,nodediff 
    Lis2 ZL points24,pr24diff
    Lis3 N nestlist 1 -c nestlst.cfg -n nestlist.*

    If a NODEDIFF or PR24DIFF arrives these files are uncompressed and the 
    DIFF will be applied.  NLUPDATE creates a zipped NODEDIFF and PR24DIFF 
    and  a  lharced  new NODELIST and  POINTS24.  The  NESTLIST  was  also 
    uncompressed.  Now,  the nodelistcompiler will be started  twice,  the 
    second time with the option line for compiling the NESTLIST.


    3)  Creating regional nodelists with the keyword PrvtI (I =  1-5). 
    You need the program PRVNODES by Gnther Paczia.

    PrvtI [A|L|Z] listname zone region

    The first flag describes the compressing method as in 2).  listname is 
    the  name of the created list and with zone,  region you specify  some 
    part of the nodelist.

    Example:

    Prvt1 Z region24 2 24

    If  a  new  nodelist is created (say NODELIST.228)  then  PRVNODES  is 
    started  with  zone  2,  region 24 as parameters and  creates  a  file 
    MYLIST.229  which is then renamed to REGION24.229, moved  into  the 
    NewList  directory and compressed with ZIP.  


    Other options in the configuration file or the commandline:

    -l/LOG: Write a report to the StatusLog

    -u/USERLIST: Start the program Pn24User.

    ====================================
    What is planned for future versions:

    Creation of various userlists.
    Rewrite diff applying code in assembler.

Included fast CRC code by Jan Kriesten
Hopefully fixed a bug which causes a crc error where no error was
File in copy statement can now include wildcards
