+% ASTROSYM.TXT : AstroSym (Version 2.20, Aug. 10, 2002) - file 1 of 8

+***************************************
+*** AstroSym : astronomical symbols ***
+***************************************
+* ( Version 2.2 --- August 10, 2002 ) *
+***************************************
+
+ASTROSYM is a font containing astronomical symbols, including those
+used for the planets, four planetoids, the phases of the moon,
+the signs of the zodiac, and some additional symbols.
+The shapes of the symbols are taken from various sources.
+For some symbols more than one shape was found - for these
+symbols variants are included.
+Some shapes were reviewed by some historians and astronomers, and the
+`main shape' reflects their preference.
+
+The main style used for the symbols in AstroSym is calligraphic (strokes
+of varying breadth). An additional version uses a uniform stroke.
+It is supplied in two variants (thin and thick strokes).
+The size of the symbols, and the breadth of the stroke, can easily
+be changed in the driver file.
+A particular set of symbols for the phases of the moon (with a `face')
+is provided in one version only.
+The MetaFont code of AstroSym uses the plain base, but is completely
+independent of the cm-fonts.
+
+The AstroSym-font contains the following characters:
+ calligraphic style:
+ \char0 - \char10 : main shape - the planetary system
+ \char11 - \char22 : main shape - the signs of the zodiac
+ \char23 - \char32 and
+ \char56 & \char57 and
+ \char68 : variant shapes
+ \char33 - \char38 and
+ \char58 - \char65 : additional astronomical and astrological symbols
+ \char69 : a variant shape
+ \char48 - \char55 and
+ \char66 & \char67 : the four main planetoids, Chiron and Lilith
+ (and variants)
+ \char10 and \char39 - \char47 : phases of the moon, and variants
+ extra symbols:
+ \char90 - \char95 : phases of the moon, with `face'
+ uniform stroke, bold : \char100 - \char169
+ uniform stroke, thin : \char200 - \char255 , \char178 - \char191
+
+This is a preliminary version.
+ The shape of some symbols may need improvement.
+ In particular, symmetric symbols are not (yet) all guarded
+ against rounding effects.
+
+Remark: The original arrangement of symbols is retained for full compatibility.
+ However, since the symbols should be used via macros,
+ this seems not to be important and
+ a more logical ordering may be used in a later version.
+
+*** version 2.20
+*** new : characters 55-69,155-169 and 178-191,255
+ including: Lilith, Chiron (2 versions),
+ three signs for Pluto (Pluto 4,5,6), and
+ (there seems to be no agreement on this sign!)
+ nine additional astronomical/astrological symbols
+Thus, version 2.20 contains 70 characters each in three styles,
+ plus 6 characters
+ (compared to 55 characters in three styles in 2.00,
+ and 29 characters in three styles in 1.00).
+*** version 2.00 (preliminary) ***
+*** new : characters 29-54,129-154,229-254 and 91-95
+ including: symbols for phases of the moon
+ six additional astronomical characters
+ Terra 2, Mars 2, Pluto 3
+ Libra 3 (enlarged symbol)
+ symbols for four planetoids
+ ( Ceres, Juno, Pallas, Vesta
+ and Ceres 2, Juno 2, Vesta 2 )
+
+The package contains the following seven files:
+ ASTROSYM.TXT this file
+ ASTROSYM.MF the driver file
+ ASTROSYM.MAC the macro file
+ ASTROSYM.CMN character definitions - common to both styles
+ ASTROSYM.CAL character definitions - calligraphic style only
+ ASTROSYM.UNI character definitions - uniform stroke only
+ ASTROSYM.XTR character definitions - extra symbols (one version only)
+ ASTROSYM.TEX sample file with symbol list (for plain TeX)
+
+Sorry, so far no .fd file for LaTeX2e is provided ( I do not use LaTeX :-)
+
+Comments and suggestions are welcome.
+Since I am curious if the font is useful (and how it looks in practice)
+I would appreciate a short message (with reference) - or even some sample
+page(s) - if it is used in a publication.

+%% History %%
+
+version 1.00 May 1, 1992 : \char 0-28,100-128,200-228
+version 1.90 March 17, 1997 (preliminary, never published)
+ added : \char 29-47,90-95,129-147,229-247
+ corrected bugs :
+ (1) font_size : cm# sharp dimension needed (pointed out by ** )
+ `cm' can cause checksum error
+ (2) [10] Luna (calligraphic) : improved calculation
+ to avoid potential arithmetic overflow
+ (reported by Jochen Cammin)
+ (3) [111] [211] Aries :
+ wrong point (Br instead of br) in computation of b
+ has caused a distorted shape
+version 2.00 February 14, 1999
+ added \char 48-54,148-154,248-254
+ corrected bugs :
+ (1) [11] slight change to avoid `strange path'
+ with certain resolutions (hopefully)
+ (2) renamed ASTROSYM.COM to ASTROSYM.CMN
+ ( extension .com has irritated some software,
+ e.g., during downloading )
+version 2.00 June 25, 2002
+ After adding various symbols (on special request) in 1997 and 1999
+ I always intended to make the new versions available on CTAN
+ (after some cleaning up, or so).
+ But, alas, this never happened :-(
+ Therefore, it probably is best to publish them as they are,
+ saving improvments for some update in the future.
+ (3) renamed ASTROSYM.DOC to ASTROSYM.TXT
+ ( to avoid confusion with Word documents :-)
+version 2.10 March 3, 1999 (never published)
+ added \char 55-65,155-165,255,178-187
+ (I did not think of this extension when publishing version 2.00.)
+version 2.20 August 10, 2002
+ added \char 66-69,166-169,188-191
+ (1) \char38,138,238 (Quadrature) : bug fix (missing semi-colon)
+ (2) \char156,157,178,179 (Pluto 4,5) : fitting signs to their box
+ ( modified macro REND
+ - this affects \char148,149,248,249 (Ceres,Ceres2) )
+ (3) the following characters produce errors for some low resolutions:
+ \char16 (Virgo) : looks usable
+ \char18 (Scorpio) : looks usable
+ \char94 (moon face: last quarter - inverse) : missing
