Subject: Use mspio for all I/O operations
X-Git-Tag: 1.0~15
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=5622fc20f0be8bff0938d24f6f45d3ab384288ca;p=builder.git

Use mspio for all I/O operations
Use GetOpt to generate help messages for options
Make --help work even if there's no package in cwd
