Xerlin has a feature which allows you to reuse elements between documents, or create templates of structures you use often. This is called the Library. You can drag any item from the Element Tree of a document into the library creating a new reusable element.
To use a Library, you first need to create a new one, or open an existing one. To create a new one, simply choose the New Library item on the File menu. Xerlin will ask for a name for the library. This is just a symbolic name you can use to keep track of different libraries. This name is used at the title of the library window. Next you will be given a Save File dialog. Choose a filename and location for the library file. Libraries are saved automatically when you close it, or when you quit Xerlin, so the file location must be determined before creating the library.
When you first have a new library, the window is empty. You must add sections to it before you can add any elements to the library. These sections provide a way to organize many items into categories. To add a new section, right-click in the library window, and choose New Section as shown in Figure 4.1
After you have a section, you can add items by drag & drop as discussed in the section called “Moving and Removing Elements” or copy and paste into the section you want to put something in.
