Package: gjdoc
Version: 0.6.1-9
Severity: normal

 Hi,

 when installing gjdoc, the javadoc and javadoc.1.gz alternatives are
 not installed.

 these are only installed when upgrading from a previous version.

 I believe the problem is within:
    if ("dpkg" "--compare-versions" "${2} " "<<" "0.6.1"); then
        update-alternatives --remove javadoc /usr/bin/gjdoc;
    fi

 While the alternatives are correctly created, they're removed because
 ${2} is empty (no previous version available).

 I think the attached patch fixes this behavior.

   Regards,
