  [1X1.1 [33X[0;0YBrief description of the package[133X[101X
  
  [33X[0;0YThe  [5XGAP[105X package [5XOpenMath[105X provides an [5XOpenMath[105X phrasebook for [5XGAP[105X: it allows
  [5XGAP[105X  users to import and export mathematical objects encoded in [5XOpenMath[105X for
  the purpose of exchanging them with other [5XOpenMath[105X-enabled applications.[133X
  
  [33X[0;0YThis manual describes:[133X
  
  [30X    [33X[0;6Yhow to view [5XOpenMath[105X representation of an object;[133X
  
  [30X    [33X[0;6Yhow  to read [5XOpenMath[105X object from stream or write it to stream for the
        purposes of exchange with another [5XOpenMath[105X-enabled application;[133X
  
  [30X    [33X[0;6Yhow to find which objects can be converted to/from [5XOpenMath[105X using this
        package;[133X
  
  [30X    [33X[0;6Yhow  to  extend  the  package  to  support  private  [5XOpenMath[105X  content
        dictionaries.[133X
  
  [33X[0;0YFor   the   detailed   information   about  [5XOpenMath[105X  standard  and  content
  dictionaries see the [5XOpenMath[105X homepage [7Xhttps://www.openmath.org[107X.[133X
  
  [33X[0;0YFor  practical purposes, the [5XOpenMath[105X package will be most efficient if used
  in  conjunction  with  the  [5XGAP[105X  package  [5XSCSCP[105X  ([KL]) which implements the
  Symbolic   Computation   Software  Composability  protocol  ([FHK+c]).  This
  protocol  specifies  an  [5XOpenMath[105X-based  remote procedure call framework, in
  which  all  messages  (procedure  calls and returns of results of successful
  computation  or  error  messages)  are  encoded  in  [5XOpenMath[105X  using content
  dictionaries  [5Xscscp1[105X and [5Xscscp2[105X ([FHK+a], [FHK+b]). Using the [5XSCSCP[105X package,
  [5XGAP[105X  can  communicate  locally  or  remotely with any other [5XOpenMath[105X-enabled
  [5XSCSCP[105X-compliant  application  which may be not only another computer algebra
  system  but also another instance of the [5XGAP[105X system or even, for example, an
  external  C/C++  or  Java  application.  Such  communication  will go into a
  seamless manner with the [5XGAP[105X/[5XOpenMath[105X conversion going in the background.[133X
  
  
  [1X1.2 [33X[0;0YInstallation of the package[133X[101X
  
  [33X[0;0YTo  use  the  [5XOpenMath[105X  package it is required to install the [5XGAPDoc[105X package
  [LN] to use the help system and parse [5XOpenMath[105X objects in the XML format.[133X
  
  [33X[0;0YTo  install  the [5XOpenMath[105X package, unpack the archive and place the [11Xopenmath[111X
  directory  in  the  [11Xpkg[111X  subdirectory  of your [5XGAP[105X4.4 installation. When you
  don't  have write access to the directory of your main [5XGAP[105X installation, you
  can  also install the package [13Xoutside the [5XGAP[105X main directory[113X by unpacking it
  inside  a  directory [11XMYGAPDIR/pkg[111X. Then to be able to load [5XOpenMath[105X you need
  to call GAP with the [10X-l ";MYGAPDIR"[110X option.[133X
  
  [33X[0;0YWhen  the  [5XOpenMath[105X  package  is  installed, it may be loaded as shown below
  (possibly loading required packages at the same time):[133X
