package require platform::shell ?1.1.3?
The platform::shell package provides several utility commands useful
for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a
specific Tcl shell different from the shell running the package. The
only requirement is that the other shell (identified by its path), is
actually executable on the current machine.
While for most platform this means that the architecture of the
interrogated shell is identical to the architecture of the running
shell this is not generally true. A counter example are all platforms
which have 32 and 64 bit variants and where a 64bit system is able to
run 32bit code. For these running and interrogated shell may have
different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify
the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository
