<Heading>Installation of &SCSCP; procedures</Heading>
There may various ways to run &SCSCP; server, for example:
<List>
<Item>
allowing generic services like evaluation of arbitrary &OpenMath; code;
</Item>
<Item>
offering highly specialized procedures like identification of groups of order 512;
</Item>
<Item>
providing access to a database of mathematical objects.
</Item>
</List>
Each of these use cases requires certain control over the level of functionality
exposed to the client. To achieve this, before starting &SCSCP; service its
provider must call the function <Ref Func="InstallSCSCPprocedure" /> to make
required procedures <Q>visible</Q> for the client.
<P/>
Additionally, the service can be made made accessible only for clients running
on the same computer, or accessible only through a particular network interface,
or generally accessible. This customization is made at the stage of starting
the &SCSCP; server with the function <Ref Func="RunSCSCPserver" />.

<Description>
This is the global record from the &OpenMath; package used for the conversion
from &OpenMath; to &GAP;. It is extended in the &SCSCP; package by adding
support for symbols from <C>scscp1</C> and <C>scscp2</C> content dictionaries
(<Cite Key="scscp1cd"/>, <Cite Key="scscp2cd"/>). Additionally,
<Ref Func="InstallSCSCPprocedure" /> adds to this record a component
corresponding to the appropriate transient content dictionary
(by default, <C>scscp_transient_1</C>) defining mappings between
&OpenMath; symbols from this content dictionary and installed &SCSCP; procedures.

</ManSection>
Actually, there is more than one way to run &GAP; &SCSCP; server:
<List>
<Item>from the &GAP; session as shown in the example above;
</Item>
<Item>starting &GAP; as <C>gap myserver.g</C>, where <File>myserver.g</File>
is the server configuration file with the last command being the call
<Ref Func="RunSCSCPserver" />, which may take its arguments from the
configuration file <File>scscp/config.g</File> (an example of such
configuration file is given in <File>scscp/example/myserver.g</File> );
</Item>
<Item>start &GAP; as a daemon using the script <File>gapd.sh</File> which
is supplied in the root directory of the package (for the description
of all available options see comments in <File>gapd.sh</File>) and
may overwrite parameters from <File>scscp/config.g</File>.
</Item>
</List>
See Section <Ref Sect="Config" /> about configuring files
<File>config.g</File> and <File>gapd.sh</File>.
