/* Information:
|
|
|
|
* This class implements a mechanism to lock a users installation directory,
|
|
|
|
* which is necessesary because instances of staroffice could be running on
|
|
|
|
* different hosts while using the same directory thus causing data
|
|
|
|
* inconsistency.
|
|
|
|
* When an existing lock is detected, the user will be asked whether he wants
|
|
|
|
* to continue anyway, thus removing the lock and replacing it with a new one
|
|
|
|
*
|
|
|
|
* ideas:
|
|
|
|
* - store information about user and host and time in the lockfile and display
|
|
|
|
* these when asking whether to remove the lockfile.
|
|
|
|
* - periodically check the lockfile and warn the user when it gets replaced
|
|
|
