Known bugs
On linux, ezcawrite will fail to write a negative number, because it interprets the "-" as a command line option flag. There are at least three workarounds. One is that you can put " -- " before the channel name and value to force getopt to stop scanning for options. Another is that you can set the "POSIXLY_CORRECT" environment variable, though this may cause side effects elsewhere. Finally, you can just put a plus sign before the minus sign, like "ezcastep FOO +-100".
