X-Install-Packager-Version (wpkg-status)

The X-Install-Packager-Version field holds the version of the packager used to first install that package. When the package gets upgraded, the X-Last-Upgrade-Packager-Version field is used instead (and this one does not get modified.)

This version can be used to know which packager was used and in case a packager was bogus, tells us that the package installation may required some maintenance.

This version is the same as the version printed out when you run this command:

wpkg --version
