+ without a trace of failure (create .rej file, print error or
+ dump core) and just ignore any further diffs.

+
+3RD PARTY PROJECTS:
+
+ * GNU indent: handle C++

+
+ * use properties for:
+ - plet?

+
+
+ * lines:
+ - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
+ - set different line sizes / thicknesses
+ - beam stem showthrough, inter beam sizes (french vs german style)
+
+ * Collisions
+ - left/right note balls should be handled by Collision:
+ < \multi 2; { \stem 1; <b c> } { <f as b> } >
+
+ * Keys:
+ - merge key{item} & localkey{item}?
+ - spacing, national styles?
