Extract shell environment after executing commands

ShellGetEnv provides facility for obtaining changes made to environment variables as the result of running shell scripts. It does this by causing a shell to invoke a series of user provided shell commands some of which might source scripts and having the shell process store its environment using a short Perl script into a temporary file, which is parsed by the ShellGetenv.

Communications with the shell subprocess may be done via standard IPC via a pipe, or may be done via the Perl Expect module necessary if proper execution of the shell script requires the shell to be attached to a “real” terminal.
