DIFFERENCES BETWEEN THE MS-DOS/MS-WINDOWS AND UN*X VERSIONS OF GED2HTML

The files "g2hdos.exe" and "g2hwin.exe" are MS-DOS and MS-WINDOWS executables,
respectively.  The MS-DOS version is useful only for small GEDCOMS of under
about 100K bytes, as the program is fairly extravagant in its use of memory,
and it does not make use of extended or expanded memory.  The MS-WINDOWS
version can process much larger GEDCOMS, depending on the amount of memory and
swap area available to the system.  As the MS-DOS filesystem appears to use a
file creation algorithm that takes time quadratic in the number of entries in
a directory, if too many files are created in one directory the program starts
to run very slowly.  Thus, under MS-DOS or MS-WINDOWS, the default is to
create several subdirectories for the individual HTML files, and to limit the
number of files per subdirectory to 100.  The default value can be
overridden with the "-d" option, and the use of subdirectories can be
completely disabled by specifing "-d 0".  In addition, under MS-DOS, the
default is to reduce the total number of HTML files by placing 10 individuals
into each file.  The number of individuals per file can be modified with the
"-n" option.  Specifying "-n 0" causes each individual to be placed in a
separate file.

Another difference in the behavior of the MS-DOS/MS-WINDOWS and the UN*X
versions of the program is that under MS-DOS and MS-WINDOWS, hyperlinks
generated by the program are converted to lower-case before inclusion in the
HTML files, and the default extension used for HTML files is ".htm" rather
than ".html".  The reason for these differences is I was getting a lot of
complaints from MS-DOS/MS-WINDOWS users who processed their GEDCOMS under
those operating systems, then uploaded their files to their WWW service
provider (usually a Un*x system), only to find that the uploading process
had converted all their file names into lower-case so that all the hyperlinks
in the HTML files failed.  I hope the modifications I have made to the program
will avoid this situation in the future.
