You can use comments to provide information about a PowerBuilder library (for example, that the library is a temporary library or used for archiving). To add or modify comments:

1. Select Modify Library Comments from the Objects menu.  The Modify Library Comments window displays the name of the current library, any comments associated with the library.
2. Review any existing comments and add or modify them if necessary. 
3. Click the OK button to save the comments and return to the Library window.
