This is a simple Windowsapp for removing newlines from a text file. It was originally released at http://zetacentauri.com and was downloaded more than 1400 times before being open-sourced.
A prebuilt Windows installer is in the installer directory:
This app requires the .NET framework 3.5 or newer.
I consider this app to be complete and it is no longer under active development. I am willing to accept pull requests if you have improvements to contribute.
