The current LM package contains the most recent version
of the Latin Modern family of fonts in the PostScript Type 1 and
OpenType format. The fonts are based on Donald E. Knuth's Computer Modern
fonts in the PostScript Type 1 format, released into public domain by the
American Mathematical Society (for the history of the outline version of
the CM fonts see, e.g., http://www.math.utah.edu/~beebe/fonts/bluesky.html ).
The project is supported by TeX users groups: CSTUG, DANTE eV, GUST,
GUTenberg, NTG, and TUG.
The current README-Latin-Modern-Math.txt says

The precise distribution conditions for these fonts can be found in

duplicate here the relevant excerpt for your convenience:
The PostScript Type 1 implementation of the Computer Modern fonts produced
by and previously distributed by Blue Sky Research and Y&Y, Inc. are now
freely available for general use. This has been accomplished through the
cooperation of a consortium of scientific publishers with Blue Sky Research
and Y&Y. Members of this consortium include:

Society for Industrial and Applied Mathematics (SIAM)
Springer-Verlag
American Mathematical Society (AMS)
In order to assure the authenticity of these fonts, copyright will be held
by the American Mathematical Society. This is not meant to restrict in any
way the legitimate use of the fonts, such as (but not limited to) electronic
distribution of documents containing these fonts, inclusion of these fonts
into other public domain or commercial font collections or computer
applications, use of the outline data to create derivative fonts and/or
faces, etc. However, the AMS does require that the AMS copyright notice be
removed from any derivative versions of the fonts which have been altered in
any way. In addition, to ensure the fidelity of TeX documents using Computer
Modern fonts, Professor Donald Knuth, creator of the Computer Modern faces,
has requested that any alterations which yield different font metrics be
given a different name.

# A new (improved?) version of the grid ADT
## Changes from the Cellular Automaton version
* If you look at `MyGrid.java`, you will notice that it no longer uses `IList<T>`/`MyList<T>` to hold the grid cells, and both `IList.java` and `MyList.java` have been removed. Instead we use standard built-in Java lists, with the `List<T>` interface (and `ArrayList<T>` as the class for new list objects).
* This saves us the work of maintaining and improving our own list, and makes it immediately compatible with useful standard Java library operations on lists.
* In general, you should always use built-in APIs (such as the Java Collections API which provides lists and similar) when available. Not only does it save time, but they're likely to be much better tested (and probably better designed) than you can do yourself, so they're less likely to have, e.g., stupid bugs that only show up in corner cases. You may also get better performance.
* You might want to do things yourself if you want to learn how stuff works; also, in some cases, there may not be a suitable API available – or the API doesn't really fully fit with what we want to do. While Java has one-dimensional lists and arrays, it doesn't really have built-in classes for grids, so we're making our own.
* An alternative to IGrid/MyGrid would be to use two-dimensional arrays – but these aren't *actually* two-dimensional arrays, but rather arrays-of-arrays, which makes them fit less well with the concept of a “grid” (the same goes for making a list of lists). In addition to being a bit inconvenient, they're also much less efficient in use – and they won't let us do useful things like “please give me the cell to the north of this cell” or “please give me all cells neighbouring this cell”.
