+The MD5 library.
+MD5 is a message digest algorithm that can be used to condense an arbitrary
+length message down to a 16 byte hash.  The functions all need to be passed
+a MD5_CTX which is used to hold the MD5 context during multiple MD5_Update()
+function calls.  This library also contains random number routines that are
+based on MD5
+
+The normal method of use for this library is as follows
+
+MD5_Init(...);
+MD5_Update(...);
+...
+MD5_Update(...);
+MD5_Final(...);
+
+This library requires the inclusion of 'md5.h'.
+
+The functions are as follows:
+
+void MD5_Init(
+MD5_CTX *c);
+	This function needs to be called to initiate a MD5_CTX structure for
+	use.
+	
+void MD5_Update(
+MD5_CTX *c;
+unsigned char *data;
+unsigned long len);
+	This updates the message digest context being generated with 'len'
+	bytes from the 'data' pointer.  The number of bytes can be any
+	length.
+
+void MD5_Final(
+unsigned char *md;
+MD5_CTX *c;
+	This function is called when a message digest of the data digested
+	with MD5_Update() is wanted.  The message digest is put in the 'md'
+	array and is MD5_DIGEST_LENGTH (16) bytes long.
+
+unsigned char *MD5(
+unsigned char *d;
+unsigned long n;
+unsigned char *md;
+	This function performs a MD5_Init(), followed by a MD5_Update()
+	followed by a MD5_Final() (using a local MD5_CTX).
+	The resulting digest is put into 'md' if it is not NULL.
+	Regardless of the value of 'md', the message
+	digest is returned from the function.  If 'md' was NULL, the message
+	digest returned is being stored in a static structure.
+
