+The logix package.
+
+This is the README for the logix package, version 2019-07-01 v1.00.
+
+This package provides supplemental symbols for use in logic and mathematics
+which are largely not present in Unicode. Some symbols are in Unicode but
+are included because they are variants that may look better in some
+applications. Logic tends not to have the complex layouts that is common for
+more general mathematics, but has different requirements for readability.
+This font is intended to complement, but not replace the AMS STIX2 fonts.
+However, it may used with any mathematical font since it does not replace or
+redefine any symbols.
+
+This is an OpenType font where all of the symbols (more than 4,000) other than
+the ASCII codepage are in the private use area. As such, the package requires
+XeLaTeX or LuaLaTeX. Not all of those symbols are directly exported, since
+there are many variants present for possible future use. While only the
+OpenType font file is usable for LaTeX, the .ttf, .woff, .woff2 and .eot font
+files are also supplied in this distribution.
+
+Other than many miscellaneous symbols, there are a large number of arrows,
+geometrical symbols, Knot drawing symbols, 64 stretchy delimiters plus a
+stretchy binding bar, of which 56 are fully stretchable. The remaining 8 are
+stretchy up to 5 times the original size. Some of the delimiters are present
+in Unicode, but their design in STIX2 does not work as well for logic. In
+particular, STIX2 delimiters tend to not extend as far below the baseline
+and above the baseline as would be desirable. Also, some STIX2 delimiters
+take more horizontal space than is necessary.
+
+There are twenty scripts, each of which (except for the two Greek scripts)
+have matching numeric, lower case and upper case glyphs. All symbols in this
+font are designed to be compatible with the STIX2 mathematical font by AMS.
+Some of these scripts overlap the Unicode math scripts, but are not intended
+to be replacements for those. Unicode does not include everything for a specific
+script -- digits or lower case may be missing, or even individual letters
+(although that may have changed). That is an issue when using a script for
+variable naming. Some script variants are omitted. Many of those variants are
+useful in logic. The scripts included are sans serif, slab serif, normal serif
+(each of these has upright, italic, bold and bold italic versions) as well as
+a calligraphic font, blackboard, fraktur (upright and bold), monospace,
+monospace italic with normal serif, and Greek (upright and italic).

+logix.otf, logix.ttf, logix.woff, logix.woff2, logix.eot and logix.vfc.
+
+To use this package, add
+
+ \usepackage{logix}
+
+it has no options. If the array package is used, it must be loaded prior to the
+logix package due to a conflict between the array package and the arydshln
+package. The public interface is defined in logix.sty and documented in logix.pdf.
+For example:
+
+ \usepackage{array} % Only if required, must load before logix.
+ \usepackage{logix} % Load logix font for supplemental symbols.
+
+ \setmainfont{STIX Two Text} % AMS STIX2 used for main font.
+ \setmathfont{STIX Two Math} % AMS STIX2 used for math font.
