-=head1 NAME
-
-remove_stale_images - remove old dvipng images
-
-=head1 SYNOPSIS
-
- remove_stale_images ARGUMENTS
-
-=head1 DESCRIPTION
-
-Remove old dvipng images.
-
-=head1 ARGUMENTS
-
-=over
-
-Arguments are optional.
-
-  --help         prints the usage message
-  --delete       delete selected images
-  --remove       same as --delete
-  --report       just report information about image dates
-
-  --days=E       final date for images considered is E days ago
-                   E can be a decimal.  E defaults to 7 days ago
-                   for deleting, and now for reporting
-  --access-dates use last-accessed date, the default
-  --modify-dates use last-modified date (probably the creation date)
-
-  --from=D       start deleting D days ago; D can be a decimal
-                   defaulting at the beginning of time
-
-
-You can also just specify E at the end of the command line.
-
-To get a status report on all of your images, use
-
-  remove_stale_images
-
-To remove all which have not been accessed in the past 10 days, use
-
-  remove_stale_images --delete --days=10
