* LICENSE.txt: added (BSD 2-clause)
* doc/units.rd, doc/units.html: updated (added entry to dcunits.txt)

(to return NumberNode.new(1) instead of ErrorNode.new(''))
Fri Feb 8 2008 T Koshiro
* lex.rb: next_token: at least one space or tab character is required
before/after 'per', 'after', 'from', 'since', 'ref'

Wed Jun 8 2005 T Horinouchi
* lex.rb:
* debug in RE_SECOND
* debug in time zone parser (many bugs)
* improvement in time parser RE_TIME to support hhmm type
in addition to [h]h:[m]m

modified +(ohter) and -(ohter) methods to use it as long as possible.
This is to widen the coverage of time -- up to now, only very
recent years (such as AD19xx-20xx) are accpeted, since the
Time intrincic class is always used.

it used to give '1 m'.
* numbernode.rb: defined == (to compare by values -- implicitly
used in the new Multi#sort)

deg_[CFK], degree[CFK], [Cc]elcius, angular_(degree|minute|secont),
[Ff]ahrenheit, farad, gravity, conventional_mercury, mercury,
Hg, hg, Julian_year, common_year, tesla

Mon Mar 1 2004 T Horinouchi
* version 1.1 released ((cvs) tag: numru-units-1_1)
Mon Mar 1 2004 E Toyoda
* test.rb: revised due to the change of reduce4; updated
* timenode.rb debugged (Unexpected generation of Float by Date#-
is avoided using Date-like wrapper to Time.)
* node.rb: unalias (such as "kilometer" -> "10^3 m") will not
occur at reduce4. (plurals still recognized in reduce4)
* namenode.rb,numbernode.rb: unused methods "nameable?" removed

unaliased to its primary name (such as "s" or "m") due to
improper parsing of dcunits.txt.

more suitable for UNumeric constraction).

Thu Feb 26 2004 T Horinouchi
* src/lex.rb: added Units#factor_and_offset
* doc/units.rd: updated

* packaging for distribution
* put Units into the NumRu module ( --> class NumRu::Units )
* cvs version control started (CVSROOT=
dennou-k.gfd-dennou.org:/GFD_Dennou_Club/ftp/arch/ruby/cvsroot
