dh_modaliases is useful for packages that ship third-party kernel modules, either in binary form, or as
       sources (with e. g. DKMS). It extracts the modules' modaliases from either the compile .ko files
       themselves (for packages which ship them in compiled form, using modinfo), or from a package file
       debian/package.modaliases (see below).

       I creates a package substitution variable "${modaliases}" which you should add to "debian/control" as

           XB-Modaliases: ${modaliases}

       This enables software which is looking for missing driver packages (such as Jockey or the operating
       system installer) to identify which package(s) will provide a driver for a piece of hardware, identified
       by its modalias.

       The standard debhelper options are supported.

       If a package ships source code (using DKMS, module-assistant, etc.) instead of compiled binary kernel
       modules, then dh_modaliases can't figure out the modaliases by scanning the *.ko files, and you have to
       provide the modalias list manually as a package file debian/package.modaliases.

       The format matches the /lib/modules/`uname -r`/modules.alias file from the Linux kernel. Examples:

           alias ssb:v1234id5678 snd_super_booster alias pci:v000010DEd0000004Esv*sd*bc03sc*i* nvidia_current

       You can generate such a list if you locally build and install this module, and then run

           modinfo mymodname | perl -nae 'print "alias $1 mymodname\n" if /^alias:\s+(.*)$/'

       (replacing "mymodname" with the actual module name).

       This program is an extension to debhelper.
