[Pkg-mozext-maintainers] build with webext

[Mechtilde Stehmann]

Hello,

To build my tree webext packages tbsync, dav4tbsync and eas4tbsync I get
these warnings:

dpkg-gencontrol: warning: Depends field of package webext-tbsync:
substitution variable ${xpi:Depends} used, but is not defined
dpkg-gencontrol: warning: Recommends field of package webext-tbsync:
substitution variable ${xpi:Recommends} used, but is not defined
dpkg-gencontrol: warning: Enhances field of package webext-tbsync:

dpkg-gencontrol: warning: Provides field of package webext-tbsync:

dpkg-gencontrol: warning: package webext-tbsync: substitution variable

dpkg-gencontrol: warning: package webext-tbsync: substitution variable
${webext:Provides} unused, but is defined
dpkg-gencontrol: warning: package webext-tbsync: substitution variable
${webext:Recommends} unused, but is defined

Can someone point me to a documentation how to fix it in a proper way?

Kind reards
