# This script is invoked when installing manual entries. It generates
# additional links to manual entries, corresponding to the procedure
# and command names described by the manual entry. For example, the
# Tcl manual entry Hash.3 describes procedures Tcl_InitHashTable,
# Tcl_CreateHashEntry, and many more. This script will make hard
# links so that Tcl_InitHashTable.3, Tcl_CreateHashEntry.3, and so
# on all refer to Hash.3 in the installed directory.
#
# Because of the length of command and procedure names, this mechanism
# only works on machines that support file names longer than 14 characters.
# This script checks to see if long file names are supported, and it
# doesn't make any links if they are not.
#
# The script takes one argument, which is the name of the directory
# where the manual entries have been installed.
