-.SH NAME
-platform::shell \- System identification support code and utilities
-.SH SYNOPSIS
-.nf
-\fBpackage require platform::shell ?1.1.4?\fR
-.sp
-\fBplatform::shell::generic \fIshell\fR
-\fBplatform::shell::identify \fIshell\fR
-\fBplatform::shell::platform \fIshell\fR
-.fi
-.BE
-.SH DESCRIPTION
-.PP
-The \fBplatform::shell\fR package provides several utility commands useful
-for the identification of the architecture of a specific Tcl shell.
-.PP
-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.
-.PP
-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.
-.PP
-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
-software.
-.SH COMMANDS
-.TP
-\fBplatform::shell::identify \fIshell\fR
-This command does the same identification as \fBplatform::identify\fR,
-for the specified Tcl shell, in contrast to the running shell.
-.TP
-\fBplatform::shell::generic \fIshell\fR
-This command does the same identification as \fBplatform::generic\fR,
-for the specified Tcl shell, in contrast to the running shell.
-.TP
-\fBplatform::shell::platform \fIshell\fR
-This command returns the contents of \fBtcl_platform(platform)\fR for
-the specified Tcl shell.
-.SH KEYWORDS
-operating system, cpu architecture, platform, architecture
