+
+BlueChips is the latest in a long line of software to make managing
+group finances easier, and would not be possible without the
+intellectual inspiration of those predecessors.
+
+CUTCAT's [accounting software][cutcat] started the trend of
+software-based accounting mechanisms. It inspired a re-implementation
+as a curses script by [Nelson Elhage][nelhage], which introduced the
+notion of "pushing expenditures" to simplify transfers. The algorithm
+used in BlueChips for settling the books is directly cargo-culted from
+Nelson's implementation.
