No need to explain this over and over again. While at it, do some other minor cleanups to whitespace and comments (i.e. delete them).

# 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.
