+Where <dsk> is a virtual disk image with an extension of:
+
+    .dsk
+    .do
+    .po
+
+NOTE: To skip always having to specify the <.dsk> name set the environment variable:
+
+           PRODOS_VOLUME
+e.g.
+   export PRODOS_VOLUME=path/to/volume.po
+
+Three different disk sizes are accepted for init
+
+   prodos test.dsk init -size=140   # 5 1/4" (140KB)
+   prodos test.dsk init -size=800   # 3 1/2" (800KB)
+   prodos test.dsk init -size=32    #HardDisk (32 MB)
+
+Examples:
+
+    prodos test.dsk ls
+    prodos test.dsk cat
+    prodos test.dsk cp    foo1 foo2 /
+    prodos test.dsk mkdir bar
+    prodos test.dsk cp    foo2      /bar
+    prodos test.dsk get   /bar/foo2
+    prodos test.dsk rm    /bar/foo2
+    prodos test.dsk rmdir /bar
+    prodos test.dsk init  /TEST
+    prodos b140.dsk init  -size=140 /BLANK140
+    prodos b800.dsk init  -size=800 /BLANK800
+    prodos b032.dsk init  -size=32  /BLANK32
