#determine_the_libreoffice_version ⇒ Object

#

determine_the_libreoffice_version

In order for this method to work, the instance variable @location_of_libreoffice must have been determined before.

That string contains the version, e. g. in a String such as “/home/x/src/libreoffice/libreoffice-7.4.2.3.tar.xz”.
