appexec - execute a command under a specified environment
appexec --env environment [options] program [program arguments]
appexec [options] environment program [program arguments]
appexec will execute a program with the specified arguments in the specified environment. The environment is generated by App::Env, so an appropriate App::Env application module must exist.

The environment to use may be specified either via the --env option, or as the first non-option argument.
The following options are available:

If this option is not specified, the first non-option argument should be the environment name
Specify a option key and value to be passed via AppOpts to the App::Env application module. This option may be specified multiple times.
Specify a site. (See App::Env for more information.)
Output the environmental variables to the standard output stream. The output format is determined by the --dumpfmt option.
The possible formats are:
bash csh ksh raw tcsh unquoted
Print the command to be run to the standard output stream before running it.
Print a short help summary and exit.
Print full documentation and exit.
