This version of &RCWA; needs at least ⪆ 4.9.0 in 64-bit mode,
&ResClasses; 4.7.0,
<Package>GRAPE</Package> 4.7 <Cite Key="GRAPE"/>,
<Package>Polycyclic</Package> 2.11 <Cite Key="Polycyclic"/>,
<Package>FR</Package> 2.2.1 <Cite Key="FR"/>,
&GAPDoc; 1.5.1 <Cite Key="GAPDoc"/>, and
<Package>Utils</Package> 0.40 <Cite Key="Utils"/>.
With possible exception of the most recent version of &ResClasses;,
all needed packages are already present in an up-to-date standard &GAP;
installation. The &RCWA; package is completely written in the &GAP; language
and can be used on all platforms for which &GAP; is available.
Like any other &GAP; package, &RCWA; is usually installed in the <F>pkg</F>
subdirectory of the &GAP; distribution. This is accomplished by extracting
the distribution file in this directory. If you have done this, you can
load the package as usual via <C>LoadPackage( "rcwa" );</C>.
<ManSection>
<Func Name="RCWATestInstall" Arg=""/>
<Returns>
<C>true</C> if no errors were found, and <C>false</C> otherwise.
</Returns>
<Description>
Performs a nontrivial computation to check whether an installation of
&RCWA; appears to work. Errors, i.e. differences to the correct results
of the test computation, are reported. The processed test file is
<F>pkg/rcwa/tst/testinstall.tst</F>.

<ManSection>
<Func Name="RCWATestAll" Arg=""/>
<Returns>
<C>true</C> if no errors were found, and <C>false</C> otherwise.
</Returns>
<Description>
Runs the full test suite of the &RCWA; package.
Any differences to the supposed results of the test computations
are reported. The processed test files are in the
<F>tst</F> subdirectory of the package directory. <P/>
Please note that the test suite is a tool for developing.
The tests are deliberately very volatile to allow to spot possible
problems of any kind also in other packages or in the &GAP; Library.
For this reason you may see reports of differences
which simply reflect improved methods in other packages or in the
&GAP; Library (for example an object may already know more of its
attributes or properties than it is expected to, or an object may
be represented in a better way), or which are caused by changes of
the way certain objects are printed, and which are therefore harmless.
However if the correct and the actual output look different
mathematically or if you see error messages or if &GAP; crashes,
then something went wrong. Also, reports about significantly
increased run times of individual commands as well as run times of
test files which are much longer than the predicted times shown
may indicate a problem.

<ManSection>
<Func Name="RCWATestExamples" Arg=""/>
<Returns> nothing. </Returns>
<Description>
Runs all examples in the manual of the &RCWA; package,
and reports any differences between the actual output and the
output printed in the manual.
