longDescription = ''
There are many (${toString ((length outputs) - 1)}) variants of color,
opacity, edge thickness, and right- or left-handedness, for this cursor
theme. This package's derivation has an output for each of these
variants, named following the upstream convention, and the attribute for
an output must be used to install a variant. E.g.:
<programlisting language="nix">
environment.systemPackages = [
comixcursors.Blue
comixcursors.Opaque_Orange
comixcursors.Slim_Red
comixcursors.Opaque_Slim_White
comixcursors.LH_Green
comixcursors.LH_Opaque_Black
comixcursors.LH_Slim_Orange
comixcursors.LH_Opaque_Slim_Blue
];
</programlisting>
Attempting to use just <literal>comixcursors</literal>, i.e. without an
output attribute, will not install any variants. To install all the
variants, use <literal>comixcursors.all</literal> (which is a list), e.g.:
<programlisting language="nix">
environment.systemPackages = comixcursors.all ++ [...];
</programlisting>
The complete list of output attributes is:
<programlisting>
${concatStringsSep "\n" variants}
</programlisting>
