 ; This file must be located in the directory with the drawings
 ; for anything to happen.
 ; Format: block name | flags ; comment
 ; If a block name is followed by a bar | and a + sign then
 ; the block will be updated from the drawing file of the
 ; same name, if one is available, and added to the xrecord.
 ; If it is followed by a bar | and a - sign then
 ; the block name will be removed from the xrecord.
 ; If there is no bar then the block will be updated.
 ; Blocks are searched for in the directory containing
 ; the current drawing and then in the rest of the acad path.
 ; Anything after a semicolon is a comment and is ignored.
