[jhbuild/desrt/master: 23/23] scripts: add a debian-mkequivs script

[Ryan Lortie <desrt src gnome org>]

commit 257a72f3228cb6eaeeb322888e05f4448e0bc9ad
Author: Ryan Lortie <desrt desrt ca>
Date:   Fri Jan 2 15:27:27 2015 -0500

    scripts: add a debian-mkequivs script
    
    Add a neat hack to generate a .deb file that depends on sysdeps of
    jhbuild.
    
    This has at least two uses:
    
     - generating a package that people can download and install with gdebi
       in order to get all build dependencies satisfied
    
     - generating a package that can be marked as a keeper in debfoster to
       keep a large number of jhbuild-required dependencies installed
       without too much additional noise
