Purpose:

Provide a developer with tips, suggestions and warnings regarding
implementing a [Tcl] [extension] using the [TEA] 2000 guidelines.

-----


   * Why bother?
   * Where is [TEA2] documented?
   * What needs to be done to move a TEA1 extension to TEA2?
   * What needs to be done to move a non-TEA extension to TEA2?
   * What tools are available to help with TEA2?
   * What do you do when TEA2 changes or is fixed?  Can you update your extension automatically?
   * On what platforms can one use TEA2 - does it work on [MacOS], [MacOS X], [VMS], [Unix], [Windows], etc.?
   * Can it build/install into paths containing spaces, e.g. ''C:/Program Files'' ?
   * On [Microsoft Windows], does the Mingw 3.x based compilers work with TEA2?

'''What tools are available to help with TEA2?'''

In a c.l.t. posting [http://groups.google.com/groups?selm=3D9B0501.BC6C84C4%40man.ac.uk] [Donal Fellows] mentioned teapot [http://www.cs.man.ac.uk/~fellowsd/tcl/teapot.tcl], the ''TEA extension help mate'' a script helping to create the configure.in , aclocal.m4 and Makefile.in for a TEA2 compliant extension.

'''Can it build/install into paths containing spaces?'''

Yes it can, but the paths have to be quoted correctly and some peculiarities may happen. 
To install in ''C:/Program Files'' one has to invoke configure like this:

 ./configure --prefix="C:/Program\ Files"

Configure seems to look for a site script in ''C:/Program\'' which is obviously incorrect, but has no negative consequences if no site script is used.
