X-Explicit (wpkg-status)

The X-Explicit field is a Boolean flag that tells you whether the package was installed explicitly (i.e. was mentioned as a command line argument) or implicitly (i.e. was found in a repository and installed as a required dependency.)

The flag is forced to Yes if you explicitly upgrade the package, otherwise an upgrade does not change the status of the X-Explicit flag.

Note that the flag is always defined. There is no default value.
