// meshRemapCmd.h
//
// Description:
//      Transfer the vertex/edge/face information from one mesh onto another.
//      The meshes are travesed based on three user supplied CVs, for each mesh,
//      The CV/edge/face information is mapped based on the traversal order within
//      each mesh.
//
// Usage:
//              meshRemap srcMesh.vtx[5] srcMesh.vtx[23] srcMesh.vtx[9] dstMesh.vtx[13] dstMesh.vtx[16] dstMesh.vtx[17]
//
// See Also:
//      meshRemapTool.cpp : this context allows you to interactively pick vertices and invoke this command
