[wpkg-users] Getting rid of install before remove

[Luca Manganelli]

Let me explain what I want to do.

1) I have Adobe-Reader-XI and Adobe-Reader-DC packages;

2) The Adobe-Reader-DC is a monster (130 MB package+cumulative update)

3) We have about 100 PC (out of 1300) that are running on a slow and 
shared link accross PC (ADSL - maximum trasfer rate 256KB/sec)

4) I'm experimenting the download of the DC package with the Microsoft 
BITS (Background Intellingent Transfer Service) that runs during the 
computer operativity;

5) So when I replace, for one host, the package Adobe-Reader-XI with the 
DC version, I do not want to uninstall immediately the XI version (so I 
removed the <remove> command), the DC setup does it automatically (so it 
starts when it has all packages in local).
