-+ * 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>.
