-/*
- * Usage
- * ~~~~~
- *
- * This simple program is aimed to be used as script interpreter in rpm
- * %post scriptlets and the like. It opens file passed as first argument
- * and executes commands found there. Only linear execution is supported.
- * For example, in glibc.spec:
- *
- * %post -p /sbin/postshell
- * ldconfig
- * -telinit q
- *
- * (full patch like /sbin/ldconfig or -/sbin/tellinit will also work).
- *
- * If command starts with - its exit status is ignored. Otherwise last 
- * non-zero exit status is returned.
- *
- * There are no builtin commands (yet :).
- *
- * Following commands *will* work as expected (as in Bourne shell):
- *
- * /bin/echo "Foo     bar baz"
- * insmod foobar options="foo bar 'qux'"
- * false
- *
- * Following *won't*:
- *
- * exit 1
- * echo foo || echo baz
- * set -x
- * 
- * Patches and bugreports are welcome, direct them to Michal Moskal
- * <malekith@pld-linux.org>.
