# libcurl
libcurl is used for downloading *.pk3 files from servers
### Windows
-Darkplaces loads `libcurl-4.dll` or `libcurl-3.dll`
-Build instructions:
-* clone https://gitlab.com/incognico/build-libcurl-windows
-* run `build.bat` in a VS2019 Development Shell
-* rename the built dlls (x64 & x86) to `libcurl-4.dll`
