                                 The most wide-spread RPM-based GNU/Linux Systems are RedHat,  
                                 Mandrake and SuSE. The documentation of these distributions  
                                 should contain information about how to install third-party  
                                 RPM packages. Nonetheless, a short summary is provided here.

                                 <para>  
                                 RPM packages can be installed applying several tools.  
                                 The most basic one is the command line program "rpm".  
                                 The hardware architecture is identified in the name  
                                 of RPM packages, eg. 'i386' for most Intel/AMD architectures.  
                                 If you have a different hardware architecture, where no  
                                 binary RPM packages are provided, you must rebuild binary  
                                 packages from the RPM source packages first (see below).  
                                 Typical rpm commands look like:  
   
                                 <programlisting>  
                                 rpm --install Thuban-0.9.0-1.i386.rpm  
                                 </programlisting>  
   
                                 Depending on what you already have installed on your  
                                 system, you are informed that some packages are  
                                 required, but not installed. You need to install them  
                                 first. Either they are provided by your GNU/Linux distributor  
                                 or available somewhere on the Internet.  
                                 The more essential and special ones are provided together  
                                 with the Thuban package.  
                                 </para>  
   
                                 <para>  
                                 For rpm exist some graphical user interfaces, notably  
                                 kpackage, GnoRPM and xrpm.

                                 <para>  
                                 Make yourself familiar with one of the tools and apply it  
                                 to install the packages.  
                                 Note, that you need to be administrator (root) for the system  
                                 to do that.

                                 <para>  
                                 This section describes howto build RPM install-packages  
                                 from RPM source-packages.  
                                 This adapts and optimizes an install-package specifically  
                                 to your system.  
                                 This is especially helpful to resolve version conflicts of  
                                 dependent packages. Furthermore, install-packages for other  
                                 platforms (e.g. PowerPC) can be created.  
                                 </para>  
   
                                 <para>  
                                 Note: rpm must be at least version 4. Execute  
                                 <literal>rpm --version</literal> to find out about the version.  
                                 </para>  
   
                                 <para>  
                                 You need to do the following preparations to be able to  
                                 build the packages as a regular user. You should now  
                                 perform the package buling as root since this  
                                 might cause damage to your system.

                                                 If you don't have a GnuPG-key, you can skip

                                 It's components are installed into the corresponding  
                                 subdirectories of your rpm-directory.  
                                 Essentially these are the sources (into directory SOURCES)  
                                 and the so-called spec-file which contains all build  
                                 instructions. The spec-file will go into the SPEC directory.  
                                 Example:

 rpm -bb thuban.spec  
                                 </programlisting>  
                                 Next, you will find the newly created package in  
                                 $HOME/myrpm/RPMS/i386.  
                                 If you build the package for another architecture than  
                                 i386, then the name of the directory has a corresponding name.

1444                            Map and legend can be exported separately in the
1445                            Thuban-Map-SVG format.
1446                            You get files that comply with
1447                            the Scalable Vector Graphics (SVG) 1.1 Specification
1448                            and can be read by many vector drawing applications.

1451                            Goal of svgexport is to provide
1452                            the start of a printing pipeline for Thuban.
1453                            For this purpose the written Thuban-Map-SVG files
1454                            contain information that can be used in postprocessing.
1455                            Typically a general vector drawing application is
1456                            more powerful then a geographic information viewer;
1457                            e.g. having much fancier symbols and fonts.
1458                            Also users benefit much more when learning to use a
1459                            more general application they can also use for other
1460                            tasks.  So the charming idea is to enable
1461                            the drawing application to postprocess a Thuban maps.
1462                            So thee xtra information in the format will make it
1463                            possible to export from Thuban and if a few geoobjects
1464                            change, and keep the general layout and style
1465                            of the full map in the vector drawing appplication.

1475                            Technical notes: the names of the layers are used

1477                            If you try to export with two layers having
1478                            the same name, you will get a name clash error.
1479                            Just change one of the layer names and try again.
