# 7zip Recipe
#

# To avoid dependency on advanced extraction tools, this recipe grabs
# 7zip binaries for Windows and replace the built-in extract mechanism 
# to allow unpacking of other formats beyond Zip files.

# SevenZip module contains the methods that replace buit-in functionality
# moved into it's own file for readability.
