+ * <p>

+ * library name to library URI, type, and options. It has the following columns:
+ * <ul>
+ * <li> Logical Library Name
+ * <li> Library Type
+ * <li> Library URI.  The full URI to the library source, form dependent on Type.
+ * <li> Options, used for access, such as password
+ * </ul>
+ * <p>
+ * The Library Type can be one of:
+ * <ul>
+ * <li> "dir"
+ * <li> "schematic"  i.e. a parts list from another schematic.
+ * <li> "subversion"
+ * <li> "http"
+ * </ul>

+ * the final dynamically assembled library table. A row in the schematic
+ * contribution to the library table takes precedence over the personal table
+ * if there is a collision on logical library name, otherwise the rows simply
+ * combine without issue to make up the applicable library table.

- * This class owns the <b>library table</b>, which is like fstab in concept and maps logical
- * library name to library URI, type, and options. It has the following columns:
- * <ul>
- * <li> Logical Library Name
- * <li> Library Type
- * <li> Library URI.  The full URI to the library source, form dependent on Type.
- * <li> Options, used for access, such as password
- * </ul>
- * <p>
- * For now, the Library Type can be one of:
- * <ul>
- * <li> "dir"
- * <li> "schematic"  i.e. a parts list from another schematic.
- * <li> "subversion"
- * <li> "bazaar"
- * <li> "http"
- * </ul>
- * <p>
- * For now, the Library URI types needed to support the various types can be one of those
- * shown below, which are typical of each type:
- * <ul>
- * <li> "file://C:/mylibdir"
- * <li> "file://home/user/kicadwork/jtagboard.sch"
- * <li> "svn://kicad.org/partlib/trunk"
- * <li> "http://kicad.org/partlib"
- * </ul>
- * <p>
- * The applicable library table is built up from several additive rows (table fragments),
- * and the final table is a merging of the table fragments. Two anticipated sources of
- * the rows are a personal table, and a schematic resident table.  The schematic
- * resident table rows are considered a higher priority in the final dynamically
- * assembled library table. A row in the schematic contribution to the library table
- * will take precedence over the personal table if there is a collision on logical
- * library name, otherwise the rows simply combine without issue to make up the
- * applicable library table.
