# Implements the "TK" standard file selection dialog box. This dialog
# box is used on the Unix platforms whenever the tk_strictMotif flag is
# not set.
#
# The "TK" standard file selection dialog box is similar to the file
# selection dialog box on Win95(TM). The user can navigate the
# directories by clicking on the folder icons or by selecting the
# "Directory" option menu. The user can select files by clicking on the
# file icons or by entering a filename in the "Filename:" entry.
