   <p>You can also build the TM by importing strings from an already existing PO file (for example one that 
has been created for the previous version of the program or web application that you are working on). That 
way, if there are similar strings in the PO file that you are working on, <app>Gtranslator</app> will display 
them in the TM panel and you can choose to use them as it is, or change/adapt them for the string you are 
translating.</p>
