# Find tclsh
#
# This module finds if TCL is installed and determines where the include
# files and libraries are. It also determines what the name of the
# library is. This code sets the following variables:
#
# ::
#
# TCLSH_FOUND = TRUE if tclsh has been found
# TCL_TCLSH = the path to the tclsh executable
#
# In cygwin, look for the cygwin version first. Don't look for it later
# to avoid finding the cygwin version on a Win32 build.
