+JPEGTOAVI
+by Phillip Bruce
+
+
+I. Introduction
+
+In the tradition of the Unix computing philosophy, here is
+yet another operator that does one simple task, namely the
+creation of an AVI MJPEG file given a list of JPEG/JFIF files.
+
+I had some difficulty in performing this extremely simple task
+in Linux, mostly because it is so simple and all of the existing
+code to do it lie at the bottom of complicated and more ambitious
+projects--e.g. xawtv, avifile, etc.  I then had to waste
+time reading M$ docs and xawtv source to find out how to do it.
+
+
+II. Installation
+
+The code is pretty basic, and so it should be pretty easy to
+install:  "make all" compiles the program, "make install"
+installs it.  If you want the files to reside in some directory
+besides /usr/local/bin and /usr/local/man, edit "Makefile".
+
+ 
+II. Usage
+
+There are three basic modes of operation:
+
+1. jpegtoavi per_usec width height img1 [img2 ... imgN]
+2. jpegtoavi -f fps width height img1 [img2 ... imgN]
+3. jpegtoavi -fsz img1 [img2 .. imgN]
+
+The first two print an AVI to STDOUT using the width and height
+parameters and the images named in chronological order.  (No
+checks are made on the validity of the JPEG/JFIFs or their
+dimensions.)  The first mode specifies the frame rate in
+terms of the period in microseconds for each frame, whereas
+the second specifies frames per second.
+
+The third mode was added to give size hints during the transfer
+of AVIs without the use of a temporary file.  Instead of
+generating the AVI it outputs the size in bytes that of the AVI
+that could have been generated.
+
+
