#*****************************************************************************
#
# Units are defined by an optional quantity and an equivalent enheter or enheter
# combination. A Python expression may be used for the quantity, but is
# restricted to using only the following operators: *, /, +, -.
# Beware of integer division truncation: be sure to use a float for at least
# one of the values.
#
# The enheter type must be placed in square brackets before a set of enheters. The
# first comment after the equivalent enheter will be put in parenthesis after the
# enheter name (usually used to give the full name of an abbreviated enheter). The
# next comment will be used in the program list's comment column; later
# comments and full line comments are ignored.
#
# Non-linear enheters are indicated with an equivalent enheter in square brackets,
# followed by either equations or equivalency lists for the definition. For
# equations, two are given, separated by a ';'. Both are functions of "x", the
# first going from the enheter to the equivalent enheter and the second one in
# reverse. Any valid Python expression returning a float (including the
# functions in the math module) should work. The equivalency list is a Python
# list of tuples giving points for linear interpolation.
#
# All enheters must reduce to primitive enheters, which are indicated by an
# equivalent enheter starting with '!'. A special "enheterless" primitve enheter
# (usualty called "enheter") has '!!' for an equivalent enheter. Circular references
# must also be avoided.
#
# Primitive enheters: kg, m, s, K, A, mol, cd, rad, sr, bit, enheter
