WinCVS Tcl Shell

Just noticed that I can enter Tcl commands in the WinCVS Output pane (see View / Output menu item). For instance …

info commands
tell socket subst open eof pwd glob list exec pid dir time eval lrange fblocked
lsearch gets case lappend proc break cvsentries variable llength …
info nameofexecutable
C:/Program Files/GNU/WinCvs 2.0/wincvs.exe
info tclversion
8.2

Useful commands for me, right now, are ls and pwd, so that I can open files or change the working directory in cmd shell.
