# Note that this program does not have any error-handling code, so if it fails, 
# you will just get some error messages at the command line. It won't skip the offending
# email and move on with the task; it will fail entirely.
#
# Keep an eye on the command prompt periodically, if you don't
# know how to write error-handling code. If it does fail, as it occassionally will
# due to a server rejecting the email, or something like that, then look in your
# Gmail 'sent' folder to identify the last email sent. Then, compare to the list
# of contacts. It will almost certainly have failed because of the next email in the list.

# An OS X shell script to fix RMagick compilation issues when using Homebrew's
# ImageMagick installation. This script creates the symlinks needed for
# RMagick to compile. Quantum depths of 8 and 16-bits are supported.
#
# You can run this script with "sh whatever_script_name.sh" in your terminal
# or with a click if you change the file extension to "command".
#
# You can manually make the links by visiting the ImagicMagick library

// Create a simple top to bottom linear gradient with a background-color backup
// The first argument, $color will be output as background-color: $color
//
// This yields a gradient that is 5% brighter on the top and 5% darker on the bottom 
//
//     +gradient-bg(#777)
//
// This yeilds a gradient where the bright and dark colors are shifted 10% from the original color.
// If you don't specify a third argument it will assign this value for the darkness too, keeping the gradient even.
