-sync_minutes=0

The -path flag accepts a list of colon-separated paths; unrooted paths are relative
to the current working directory. Each path is considered as an additional root for
packages in order of appearance. The last (absolute) path element is the prefix for
the package path. For instance, given the flag value:
path=".:/home/bar:/public"
for a godoc started in /home/user/godoc, absolute paths are mapped to package paths
as follows:
/home/user/godoc/x -> godoc/x
/home/bar/x -> bar/x
/public/x -> public/x
When godoc runs as a web server, it creates a search index from all .go files
under $GOROOT (excluding files starting with .). The index is created at startup
under -goroot (excluding files starting with .). The index is created at startup
and is automatically updated every time the -sync command terminates with exit
status 0, indicating that files have changed.
