General Description: The Cygwin website defines Cygwin as:
“…  a Linux-like environment for Windows. It consists of two parts:
	- A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
 
	- A collection of tools which provide Linux look and feel. “
 
Cygwin.com further explains what Cygwin is not:
	- “Cygwin is not a way to run native linux apps on Windows. You have to rebuild your application from source if you want it to run on Windows.
 
	- Cygwin is not a way to magically make native Windows apps aware of UNIX ® functionality, like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality.”
