I personally would prefer a compression that uses solid archives, nobody 
needs to just extract one file, we need them all. Maybe we can create a 
new container format, that includes the dependencies of the package at a 
specified position at the beginning of the file and then the compressed 

I'm thinking of a xml based package, it would look a bit like this:

<rospckg version="1.0">
       <+ package="freeldr"> //this package is required
         <minver>1.0</minver>  //it has to be at least this version
         <maxver>1.2.1</maxver>  //any version higher than this one is 
not allowed
         <notver>1.0.1b;;1.1.1-badver</notver>  //these versions 
are not allowed
       <- package="ntldr">  //there is a conflict, these two packages 
can't be installed at the same time
         <exceptver>2.0.1-ros</exceptver>  //but this one IS allowed
       <shortdesc>This is one sentence about this app</shortdesc>
       <extdesc>Put the long description here, there is no 
     <install base="%SYSTEMROOT%" type="7zip">
       Here will be one compressed archive that will be unzipped to 
     <install base="%WHATEVER%" type="tar"
       And a tar archive...
     <script type="registry">
       Some registry values...
     <script type="batch">
       and a batchfile...
