+IMPORTANT - The programs on this disk will ONLY WORK on a PC with a 386
+or better processor. See the Technical Notes section for details of why.
+<P>
+Directions:
+<P>
+<OL><LI>
+ Create a directory on your hard disk.
+ e.g. mkdir ALSCRIPT.
+<P>
+<LI>
+ Copy the Contents of the floppy disk into this directory.
+<PRE><TT>
+ e.g. copy a:*.* c:\alscript.</TT></PRE>
+<P>
+<LI>
+ Edit your AUTOEXEC.BAT file and add
+<PRE><TT>
+ C:\ALSCRIPT to your path.</TT></PRE>
+<P>
+<LI>
+ Edit your AUTOEXEC.BAT file and add the following two lines.
+ set DOS4GVM=@ALSCRIPT.VMC
+ set DOS4G=quiet
+</OL>
+<P>
+The first line is an instruction to read instructions from the file
+ALSCRIPT.VMC. This sets up a permanent swap file on your hard disk.
+By default, the swap file is about 12MBytes in size. If you do not have
+this much free space on your disk, then edit the ALSCRIPT.VMC file
+to reduce the swap file size, or alternatively, do not put this line
+in your autoexec.bat.
+<P>
+The programs will run without this swap file, but you will be limited in
+ the size of alignment you can process by the amount of RAM you have
+installed. I have only tested this program on a 486/33 with 8MBytes RAM
+and a 386/33 with 4MBytes so I do not know the practical limitations of
+machines with smaller memories. Any feedback would be appreciated.
+<P>
+5. Type AUTOEXEC.BAT to initialise the changes, or better still, reset
+the computer.
+<P>
+6. You should now be able to run all three programs in the package from
+anywhere on your disk. msf2blc, clus2blc and alscript. If you get
+memory allocation errors when you try to run alscript, then use the
+MAX_NSEQ and MAX_SEQ_LEN commands to reduce the default limits. If the
+program still won't run, then think about buying some more memory!!
+<P>
+The programs msf2blc and clus2blc should run OK, but if you try to
+process alignments that are too large for your computer, you may get a
+"malloc error" which will stop the program. If this happens and you are
+not using the virtual memory option discussed above, then try adding the
+line set DOS4GVM=@filename to your autoexec.bat file. If you
+don't have enough disk space to do this, then buy a bigger disk, or more
+memory.
