 In addition to all of [my libraries](https://github.com/nothings/stb), there are other, similar libraries.

 **Public domain single-file libraries usable from C and C++ are in bold.** Other libraries are either non-public domain,

+or two files, or only usable from C++, or all three. Libraries of more than two
+files are mostly forbidden.
 
 For the API column, "C" means C only, "C++" means C++ only, and "**C**" means C/C++;
 I use this notation to keep the column a little narrower than "C/C++" would be.
 (As of this writing, the API is unknown for many libraries, and the benefit of the doubt
 is given for boldfacing.)
 
+Submissions: I accept submissions (as issues or as pull requests). Please note that every
+file that must be included in the project counts; a header and a source file is 2 files,
+but a header file, source file, and LICENSE (if the license isn't in the source file) is 3
+files, and won't be accepted, because it's not 2 files. But actually 'LICENSE' is a problem
+for just dropping the library in a source tree anyway, since it's not scoped to just the
+library, so authors are encouraged to include the license in the source file.
