Support for cross-shell testing added, via option `-s <shell>` and env. variable `TEST_SHELL`. * For tests that _source_ shell scripts: option `-s <shell>` now tells urchin to invoke test scripts with the specified shell (only shebang-less and `#!/bin/sh` tests scripts). * For tests that _invoke_ schell scripts: instruct users to write their tests to always invoke via environment variable `TEST_SHELL` (e.g., `$TEST_SHELL ../foo`), and invoke urchin with that variable defined as needed, e.g., `TEST_SHELL=ksh urchin ./tests`; urchin defaults `TEST_SHELL` to `/bin/sh`. See updated `readme.md` for details. 2014-10-17 21:16:12 +00:00			`#!/bin/sh`
