+
+      doz --- a converter; converts decimal numbers into dozenal. Accepts
+         input in standard or exponential notation (i.e., "1492.2" or "1.4922e3").
+      dec --- a converter; converts dozenal numbers into decimal. Accepts input
+         in standard or exponential notation (i.e., "X44;4" or "X;444e2").
+      dozword --- converts a dozenal number (integers only) into words,
+         according to the Pendlebury system.
+      dozdc --- a full-featured scientific calculator which works in the
+         dozenal base. RPN command line.
+      tgmconv --- a converter for all standard measurements; converts to and
+         from TGM, Imperial, customary, and SI metric.
+      dozpret --- a pretty-printer for dozenal numbers; inserts spacing (or
+         other characters) as desired, and can also transform transdecimal digits
+         from 'X' to 'E' into any character or sequence of characters desired.
+      dozdate --- a more-or-less drop-in replacement for GNU and BSD date, it
+         outputs the date and time in dozenal, as well as containing some TGM
+         extensions.
+      dozstring --- a simple byte converter; absorbs a string either from
+         standard input or a command line argument, leaving it identical but
+         for the numbers, which it converts into dozenal. Options for padding
+         and for not converting specific numbers.
+      doman --- a converter which takes a dozenal integer and
+         emits its equivalent in a non-place-value system, such as
+         Roman numerals.  Arbitrary ranks and symbols may be used.
+         Defaults to dozenal Roman numerals.
