Eagle Library Import
To import your library into Eagle, first go to the main menu bar and
click on File. From there go
to New, and from that
drop-down list select Library.
Now a new blank library window will appear. From here, click on File, and then select Script from the drop-down list.
You'll be presented with a dialog box to select a file. Navigate to
the folder where your Ultra Librarian library was exported to, then
select the corresponding .scr
file and click Open. The
exported script will then populate the new library with the data from
your exported library. Once this finishes you will see the components
in the library window.
