# yume example: Click "import" to save a screenshot as next-numbered
# jpg file in $SS directory.

# Parameters:
# PIXDIR can be specified by parameter 1, or defaults to ~/pix.
# PREFIX can be specified by parameter 2, or defaults to "screen-"
# DELTA  can be specified by parameter 3, or defaults to 10.
# Parameter #4 should be blank or 'T'.
 
#  A file with extension .val is used to keep track of numbers.  If no
#  such file exists, 1100.val is created, giving (typically) 1110.jpg
#  as the first name created.  If a name conflict occurs, the number
#  will be incremented until no conflict exists.
