Copied from the Notepad++ homepage:


Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several languages.
Running in the MS Windows environment, its use is governed by GPL License.

Based on the powerful editing component Scintilla, Notepad++ is written in C++ and uses pure Win32 API and STL which ensures a higher execution speed and smaller program size. By optimizing as many routines as possible without losing user friendliness, Notepad++ is trying to reduce the world carbon dioxide emissions. When using less CPU power, the PC can throttle down and reduce power consumption, resulting in a greener environment.

This project is mature. However, there may be still some bugs and missing features that are being worked on. If you have any questions or suggestions about this project, please post them in the forums.
Also, if you wish to make a feature request, you can post it there as well.
But there's no guarantee that I'll implement your request.

You're encouraged to translate Notepad++ into your native tongue if there's not already a translation present in the Binary Translations page.
And if you want, help translating Notepad++ official site into your native tongue would be greatly appreciated.

I hope you enjoy Notepad++ as much as I enjoy coding it.

Comments from the uploader (olofolleola4):
This is some sick shit that happened in summer 2010:
"Under the pretext of cryptographic exportation control, US government made the major FOSS hosts (SourceForge, Google code, Fedora, etc...) in USA territory comply with the Export Administration Regulations (http://www.bis.doc.gov/encryption/pubavailencsourcecodenofify.html). As a result they reject the access of FOSS resources from the 5 countries (Cuba, Iran, North Korea, Sudan, and Syria) in the "black list" of US government.

It's not the first time that a government try to control Internet access to protect its interest. One of most famous examples is the Grand Firewall of China. Obviously the US government is walking into the footsteps of the Chinese government. In our case it's about the violation of FOSS community's right, we cannot just let it happen without doing something. It should never be any government to decide who has the access right to FOSS resource and who has not.

A walk around from SourceForge:
After complying with this law, SourceForge provided an option "Export Control: non-encryption algorithms included". A mail to make this option explicit was sent to all project managers on SF recently. It's the only FOSS host who offers such walk around as far as I know. We appreciate all their efforts and we will keep our binary releases on SourceForge."

NOBODY SHOULD CENSOR FOSS!!!
