|Unfortunately, this is no longer accurate for Unix 5.4 (SVR4).
|The files that need to be changed are still valid
|(/etc/conf/cf.d/?(mtune|stune)), but the value that controls

	Where will one find these files in the
	System V release 4 version for the Amiga?

|file size limit (nee ULIMIT) has changed.  As of SVR4, the complete
|BSD-style resource limit capability has been implemented.  To
|change what is commonly considered ULIMIT, you need to change
|the entries SFSZLIM (for soft limit) and HFSZLIM (for hard limit).
|They are close to the bottom of the mtune file, along with some 
|comments (!!) that describe what they are.  These limits are in
|bytes, rather than blocks, and a value of 0 is no longer used
|to mean unlimited.  Unlimited is now MAXINT.
|
|Note that the ULIMIT entry in /etc/default login should still
|work, and the shells still understand the ulimit command.  For
|a quick peek at the new features, to a "ulimit -A" to ksh.
|Unfortunately, the values are printed in blocks for compatibility,
|so be prepared for some confusion.

	That seems to be "ulimit -a" here...
