2 August, 2004: started conversion to NASM;
		report version as 2.30.
9 August, 2004: get attributes (redir 0f) returns size, time & date.
10 August, 2004: modified finding volume label (consistent with MSCDEX):
		   the attribute must equal 8 (NOT bit 3 set)
		   the label is always returned first (dir/pattern is ignored)
		   the search then continues as normal
12 August, 2004: fixed tilde usage not being set properly; allow AX != 0.
?? August, 2004: added /L:<letter>.
22 September, 2004: really fixed tilde usage (can't use AX, idiot!).
25 September, 2004: don't know what the hell I was thinking with that tilde
		     usage, I should read my own docs (the above used CH to
		     both set and get, now I've reverted back to BX for state);
		    released first 3.00 beta.

29 September, 2004: fixed bug in option processing (failed multiple /D).
5 October, 2004: fixed bug with /C and LH with three or more drives.
7 October, 2004: fixed bug displaying wrong device name if unable to open;
		 added /Q[Q] option, for quiet operation;
		 refuse non-CD drivers;
		 added /V option to display memory usage.
8 October, 2004: added /D:Drives option to reserve/remove drives;
		 added /R option to determine read-only attribute;
		 due to above, made read-only the default.
11 October, 2004: added get/set read-only attribute to the API.

12 October, 2004: Released beta 2 (including all programs).

14 October, 2004: fixed bug with tildes (NASM optimisation ruined inline data);
		  added Joliet code.
18 October, 2004: fixed bug in locating files (FindEntry was using SHL not SHR);
		  couple more size optimisations (code rearranging).
9 November, 2004: remove trailing slash when changing directory.
11 November, 2004: added DRDOS define to work around the INSTALL problem.
12 November, 2004: fixed problem with Int2F/AX=11FF;
		   use normal "D:\" instead of "\\D.\A.\" (define CDROOT).
13 November, 2004: allow one level of nesting (define CDIMAGE); this lets an
		    image be on a CD.
15 November, 2004: fixed problem retrying critical error (preserve ES);
		   fixed redirector chaining problem (couldn't run programs on
		    a network drive; problem was with RD_Read PUSHing CX,
		    upsetting the return address discards).
16 November, 2004: fixed uninstall (ClrRoot wasn't called correctly);
		   install if drives were reserved, but no devices were found;
		   recognise number of drives being zero.
17 November, 2004: display number of drives available;
		   prefix driver name with '*' to ignore and reserve;
		   removed VARBLKSIZE and associated file test.
19 November, 2004: removed VLabel from DrvEnt, use FName within RootEnt;
		   SMARTDrive check returns size of DrvEnt in DX;
		   modifed SMARTER to suit both of above (rerun!).
23 November, 2004: fixed bug with RedirForUsFlag (40h might not be set; close
		    would fail sometimes);
		   DRDOS define no longer needed (dynamically relocate code).
26 November, 2004: fail my invalid API calls (for future compatibility).
27 November, 2004: [/?] /V displays compile- and run-time options;
		   changed default driver to SHSU-CDH.
28 November, 2004: modified SMARTDrive check (BX enters with 0BABEh and
		    returns with compile-time flags).
29 November, 2004: verify resident and executable compilations match.


SHSUCDHD:
10 October, 2004: added /V option to display memory usage.

24 October, 2004: fixed Link when using i8086 (mmovd corrupting DX).

		  fixed bug in calculating i8086 file position;
		  fixed bug with unknown unit/cmd error (using B1, not B9);

15 November, 2004: refuse to install if bad image; prefix name with '?' to

		    root paths);
		   preserve flags on interrupt entry;
		   allow INSTALL on DR-DOS;
