Subject: add 'run' command to tahoe
X-Git-Url: https://git.rkrishnan.org/pf/content/en/seg/cyclelanguage?a=commitdiff_plain;h=8f4f3bf6cc20f9644e42ec9a992743dc14e96593;p=tahoe-lafs%2Ftahoe-lafs.git

add 'run' command to tahoe

adds a 'run' commands to bin/tahoe / tahoe.exe
it loads a client node into the tahoe process itself,
running in the base dir specified by --basedir/-C and
defaulting to the current working dir.

it runs synchronously, and the tahoe process blocks until
the reactor is stopped.
