/*
CopyPath.m -- Services program for Workspace to make a cd command
using the current path, and copy that onto pasteboard in
plain ASCII.
This is for pasting in a cd command into a shell.
Copy in Workspace doesn't work for this purpose, because
the copied pathname is NXFilenamePboardType, rather than
NXAsciiPboardType required by Terminal and Stuart.
This app has no GUI.
No Copyright is claimed.
This program is hereby released into the public domain.
10-30-91, Version 1.0 Izumi Ohzawa.
11-07-91, Condensed and modified by Daniel Faken - Main differences:
1) Optimised. (You ask Why? Why not.)
3) No Workspace-owned icon-tile pops up, due to a .daemon extension.
4) Doesn't exit after pasting. (Can't see it anyhow, so why exit?)
5) I ask that you keep at least brief mention of my name on this.
11-12-91, Version 1.1 Izumi Ohzawa.
Grafted back separate cd command making code, etc.
11-20-91, Version 1.2 Eric P. Scott.
Removed unused .h file.
Removed all references to Application Class.
Removed Window posing nonsense.
Converted internal method to C procedure.
Added more intelligent shell quoting.
Added pushd option.
1-08-92, Version 1.3 Michael Cohen (mcohen@acoustic-srx.ntt.jp)
Fixed for multiple browser selection.
