| 16 | plugins to use, what parameters to pass to them, and in what order
|

| 17 | they occur. Under "Design Sections", click "Document Plugins".

| 84 | To add a plugin, select it using the "Select plugin to add" pull-down list near the
|
|---|
| 85 | bottom and then click "Add Plugin". A window appears entitled
|
|---|
| 86 | "Configuring Arguments"; it is described later. Once you have configured the
|
|---|
| 87 | new plugin, it is added to the end of the "Currently Assigned Plugins" list.
|
|---|
| 88 | Note that a plugin may only occur once in the list.
|
|---|
| 89 | <p></p>
|
|---|
| 90 | To remove a plugin, select it in the list and click "Remove Plugin".
|
|---|
| 91 | <p></p>
|
|---|
| 92 | Plugins are configured by providing arguments. To alter them, select the
|
|---|
| 93 | plugin from the list and click "Configure Plugin" (or double-click
|
|---|
| 94 | the plugin). A "Configuring Arguments" dialog appears with three parts: a
|
|---|
| 95 | text field for entering custom arguments, an area containing controls for
|
|---|
| 96 | specifying arguments, and two buttons at the bottom.
|
|---|
| 97 | <p></p>
|
|---|
| 98 | There are different kinds of controls. Some are checkboxes, and clicking one
|
|---|
| 99 | adds the appropriate option to the plugin. Others are text strings, with a
|
|---|
| 100 | checkbox and a text field. Click the box to enable the argument, then type
|
|---|
| 101 | appropriate text (regular expression, file path etc) in the box. Others are
|
|---|
| 102 | pull-down menus from which you can select from a given set of values. Still
|
|---|
| 103 | others allow multiple selections from a list. To add a value, select it and
|
|---|
| 104 | click "Add"; to remove it, select it and click "Remove". To learn what an
|
|---|
| 105 | argument does, let the mouse hover over its name for a moment and a description
|
|---|
| 106 | will appear.
|
|---|
| 107 | <p></p>
|
|---|
| 108 | When you have changed the configuration, click "OK" to commit the changes and
|
|---|
| 109 | close the dialog, or "Cancel" to close the dialog without changing any plugin
|
|---|
| 110 | arguments.
|
|---|
| 111 | <p></p>
|
|---|
| 112 | The plugins in the list are executed in order, and the ordering is sometimes
|
|---|
| 113 | important. Two plugins, ArcPlug and RecPlug, are vital to the collection
|
|---|
| 114 | building process, and are fixed in place at the end of the list (with a
|
|---|
| 115 | separator line). To change the ordering of the other ones, select the plugin you want to move
|
|---|
| 116 | and click "Move To Top", "Move Up", "Move Down", or "Move To Bottom".

|

| 120 | The Librarian Interface does its best to determine what arguments a plugin
|
|---|
| 121 | supports. However, there may be cases where the user wants to specify special
|
|---|
| 122 | arguments, and for this a text field called "Custom Arguments" (at the top) is
|
|---|
| 123 | provided. Any text in it is appended verbatim to the end of the plugin
|
|---|
| 124 | command.
