# reverse polish notition calculator using curses
# by Shiar <shiar.org>
-# 1.01 06-18 - start (curses, some basic commands)
-# 1.02 06-20 - function keys select command/submenu from (sub)menu
-# - backspace to undo last digit
-# 1.03 06-25 - values displayable in arbitrary base
-# - can enter fractions (.) and negative values (_)
-# 1.04 08-04 14:45 - error dialog (don't mess up screen)
-# - manual command input using capital letters
-# - ^L redraws screen
-# pre 09-09 22:00 - overhaul in stack handling
-# 1.05 09-10 19:45 - hp48-like drop (backspace but not editing value)
-# - error on insufficient arguments for command
-# - command backspacing
-# - some unit conversion (mostly lengths) from menu
-# - q for sq(rt) (formerly quit, now only ^D/quit)
-# 1.06 09-15 23:10 - menu contents in module
-# - new commands: a?(sin|cos|tan)h, inv, !, rand
-# - x and v shortkeys
-# 1.07 09-24 23:50 - numeric modifiers hardcoded instead of in action hash
-# - action undo: last stack alteration can be undone
-# - enter on no value repeats last val on stack
-# - new commands: sr/sr, shortkeys ( )
-# 1.08 09-26 22:10 - additional digits were not correctly applied to negative values
-# - negative numbers displayed correctly in different bases
-# - second undo redoes
-# - fixed %
-# - stack command (cursor up) cycles through values in stack
-# 09-27 00:57 - all key aliases moved to module DCT::Bindings

+VERSION HISTORY
+1.01 06-18 - start (curses, some basic commands)
+1.02 06-20 - function keys select command/submenu from (sub)menu
+ - backspace to undo last digit
+1.03 06-25 - values displayable in arbitrary base
+ - can enter fractions (.) and negative values (_)
+1.04 08-04 14:45 - error dialog (don't mess up screen)
+ - manual command input using capital letters
+ - ^L redraws screen
+ pre 09-09 22:00 - overhaul in stack handling
+1.05 09-10 19:45 - hp48-like drop (backspace but not editing value)
+ - error on insufficient arguments for command
+ - command backspacing
+ - some unit conversion (mostly lengths) from menu
+ - q for sq(rt) (formerly quit, now only ^D/quit)
+1.06 09-15 23:10 - menu contents in module
+ - new commands: a?(sin|cos|tan)h, inv, !, rand
+ - x and v shortkeys
+1.07 09-24 23:50 - numeric modifiers hardcoded instead of in action hash
+ - action undo: last stack alteration can be undone
+ - enter on no value repeats last val on stack
+ - new commands: sr/sr, shortkeys ( )
+1.08 09-26 22:10 - additional digits were not correctly applied to negative values
+ - negative numbers displayed correctly in different bases
+ - second undo redoes
+ - fixed %
+ - stack command (cursor up) cycles through values in stack
+1.09 09-27 00:57 - all key aliases moved to module DCT::Bindings
+ 09-29 12:15 - number of menu items depends on screen width
+ 10-11 21:30 - hooks allowing for extra code at reload, showentry, and precmd
+ 21:50 - all menu related functions moved to menu.pm
+ 22:05 - unit conversion out of main program (entirely into unitconv.pm)
+ 10-12 01:50 - backspace becomes "back" (soft drop, like old "drop")
+ - normal drop command (alt+bs) removes input/stack value at once
+ 02:13 - $val{frac} default undefined instead of 0
