Subject: Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+/* Put data into the proc fs file.
+ * 
+ * Arguments
+ * =========
+ * 1. The buffer where the data is to be inserted, if
+ *    you decide to use it.
+ * 2. A pointer to a pointer to characters. This is
+ *    useful if you don't want to use the buffer
+ *    allocated by the kernel.
+ * 3. The current position in the file
+ * 4. The size of the buffer in the first argument.
+ * 5. Write a "1" here to indicate EOF.
+ * 6. A pointer to data (useful in case one common 
+ *    read for multiple /proc/... entries)
+ *
+ * Usage and Return Value
+ * ======================
+ * A return value of zero means you have no further
+ * information at this time (end of file). A negative
+ * return value is an error condition.
+ *
+ * For More Information
+ * ====================
+ * The way I discovered what to do with this function
+ * wasn't by reading documentation, but by reading the
+ * code which used it. I just looked to see what uses
+ * the get_info field of proc_dir_entry struct (I used a
+ * combination of find and grep, if you're interested),
+ * and I saw that  it is used in <kernel source
+ * directory>/fs/proc/array.c.
+ *
+ * If something is unknown about the kernel, this is
+ * usually the way to go. In Linux we have the great
+ * advantage of having the kernel source code for
+ * free - use it.
