Enable better build-time flexibility over which WinSock to include
[u/mdw/putty] / scp.c
1 /*
2 * scp.c - Scp (Secure Copy) client for PuTTY.
3 * Joris van Rantwijk, Simon Tatham
4 *
5 * This is mainly based on ssh-1.2.26/scp.c by Timo Rinne & Tatu Ylonen.
6 * They, in turn, used stuff from BSD rcp.
7 *
8 * Adaptations to enable connecting a GUI by L. Gunnarsson - Sept 2000
