+spalign version dated 2016-10-05
+================================
+
+The purpose of this package is to decrease the number of keystrokes needed to
+typeset small amounts of aligned material (matrices, arrays, etc.). For
+instance, it is inconvenient to type (using the `amsmath` package)
+```latex
+\[\begin{matrix}
+ 1 & 12 & -3 \\
+ 24 & -2 & 2 \\
+ 0 & 0 & 1
+ \end{matrix}\]
+```
+in a document where several hundred such matrices must be typeset. Of course
+one can always define a macro `\mat` which puts its argument inside a `matrix`
+environment, but it is still necessary to type the align character `&` and the
+end-of-row control sequence `\\` many times for each matrix.
+
+This package provides a facility for typesetting matrices, and for using other
+alignment environments and macros, with spaces as the alignment delimiter and
+semicolons (by default) as the end-of-row indicator. So the above matrix could
+be produced using the command:
+```latex
+\[ \spalignmat{1 12 -3; 24 -2 2; 0 0 1} \]
+```
+This package also contains utility macros for typesetting augmented matrices,
+vectors, arrays, systems of equations, and more, and is easily extendable to
+other situations that use alignments.
