[ The Makefiles had ESCAPE and \r characters in their comment lines;
I changed them to their printable representation, the two-character
sequences ^[ and ^M, respectively. Also, the file ascii2var/uu.test.var
had some non-ASCII characters in it; I used uuencode; the resultant
file is really ascii2var/test.var. Also, I do not have C++ nor any
images, so I have not tested this package. --r$ ]
