           admb simple

            simple

and have everything just work.  this can be done with the inno installer
so that all the differences between
compilers are hidden from the user. except for the compiler it should
not be necessary to add any more software.
the reason that tpl2cpp or tpl2rem was looking for cat is that is was
the mingw32 version which  was originally intended
for cygwin whihc has these tools. the "true" windows version uses   copy
instead of cat.

It is really only necessary to have one verion of tpl2cpp and tpl2rem
for windows and another for Linux
so that part should be removed from the build of each version and just
copied into the bin file.  Is is necessary to
have a copy of sed.exe for whihc I use a mingw version. I have had
better luck with mingw32 than with cygwin when moving to 64bit XP.

However it is important to be able to use more than one compiler on the
same machine.
first consider how to set up the effortless install  I mentioned above.
I think the best way is to have the installer define a (global)
environment string like ADMB_HOME to
point to the directory where admb is installed. To run the software the
shell script admb.bat is copied to the
system directory know as {sys} to the Inno installer.  It can figure out
where this shold be for different
version of windows. for example something like c:\winnt\system32.  this
is already on the users path
so that it will be found when the user types in  admb  simple
the user may have to reboot to get the command shell window to "see" the
new ADMB_HOME,
but windows users are used to rebooting.

If the installation detects that the user already has ADMB_HOME defined
and/or admb.bat in {sys}
it can use a variant such as a compiler specific name such as 
ADMB_VC8_HOME  and admb_vc8.bat
It should of course notify the user that there is already one version of
ADMB installed and that it is doing the curretn install in this way.

this works for different compilers so long as the compler shell command
are different. for example for vc++
is is cl.exe for borland it is bcc32.exe and for mingw32 it is gcc and g++.

If one needs say two different versions of g++ one can find the bin
directory conatining it and do a copy

     copy "g++.exe"  "g++421.exe"

and use g++421 in the admb_gcc421.bat file.
