  35. This script is intended to be used with @require, for Greasemonkey scripts
  36. using "@grant none".  It emulates the GM_ APIs as closely as possible, using
  37. modern browser features like DOM storage.
  38.  
  39. Scripts should plan to remove usage of GM_ APIs, but this shim offers a
  40. short-term workaround to gain the benefits of running in the security
  41. restriction free "@grant none" mode before that is completed.
  42.  
  43. Read the comments on each function to learn if its emulation is good enough
  44. for your purposes.
