# This script creates a complete godoc app in $APPDIR.
|
|
# It copies the cmd/godoc and src/go/... sources from GOROOT,
|
|
# synthesizes an app.yaml file, and creates the .zip, index, and
|
|
# configuration files.
|
|
#
|
|
# If an argument is provided it is assumed to be the app-engine godoc directory.
|
|
# Without an argument, $APPDIR is used instead. If GOROOT is not set, "go env"
|
|
# is consulted to find the $GOROOT.
|
|
#
|
|
# The script creates a .zip file representing the $GOROOT file system
|
|
# and computes the correspondig search index files. These files are then
|
|
# copied to $APPDIR. A corresponding godoc configuration file is created
|
|
# in $APPDIR/appconfig.go.
