== Pakkevejledning ==
Her beskrives hvordan man kommer fra kildekoden til en pakke der kan bruges i installationsvejledningen.

 1. Export source fra repository{{{
svn export https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/xcorrSound_v1.01}}}
 1. Kør{{{
./createtarball.sh}}}
 1. Nu kan tjærebolden (xcorrSound.tar) distribueres.

== Installationsvejledning ==
Beskrivelse af hvordan man bygger og installerer programmet på en given maskine.
 1. Export XcorrSound{{{
svn export https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/xcorrSound_v1.01}}}
 1. Go to the 'xcorrSound/fftw-3-2-2' folder.
 1. Run the following{{{
./configure --prefix=<fftw>
make
make install}}}
where {{{<fftw>}}} is the subfolder ''fftw'' where xcorrSound_v1.01 was checked out. fx
{{{/home/larm/jsn/xcorrSound_v1.01/fftw}}}
 1. go to the 'xcorrSound' folder.
 1. Run{{{
make xcorrSound}}}
 1. Test that it works: (should print out how to use this tool){{{
./xcorrSound}}}


== Anvendelse ==
