+ *	Modifications for MSVC: Yasuhiro Matsumoto
+ *
+ *	This source code is released into the public domain. It is provided on an
+ *	as-is basis and no responsibility is accepted for its failure to perform
+ *	as expected. It is worth at least as much as you paid for it!
+ *
+ * tee.c - pipe fitting
+ *
+ * tee reads stdin, and writes what it reads to each of the specified
+ * files. The primary reason of existence for this version is a quick
+ * and dirty implementation to distribute with Vim, to make one of the
+ * most useful features of Vim possible on OS/2: quickfix.
+ *
+ * Of course, not using tee but instead redirecting make's output directly
+ * into a temp file and then processing that is possible, but if we have a
+ * system capable of correctly piping (unlike DOS, for example), why not
+ * use it as well as possible? This tee should also work on other systems,
+ * but it's not been tested there, only on OS/2.
+ *
+ * tee is also available in the GNU shellutils package, which is available
+ * precompiled for OS/2. That one probably works better.
