bashfoo-bundle

##
## bashfoo-bundle - bash linker
##
##    creates self-contained bash script bundle by linking all required scripts
##
## usage
##    bashfoo-bundle MODULE [MODULE ...]
##
## Requirements for modules are specified as `bashfoo-source MODULE` phrases contained
## somewhere in script (usually at top, as comments).
##
## Example:
##  foo.sh:
##    foo() {
##      echo foo
##    }
##  script.sh:
##
##    # bashfoo-source foo.sh
##    # bashfoo-source
##
##    foo
##
## The `bashfoo-bundle script.sh` will create concatenation of `foo.sh` and `script.sh`.
## The dep tree is traversed in depth-first order.
