-WebTry
-======
-
-Allows trying out Skia code in the browser. Run a local webserver
-and from the pages it serves try out Skia code and see the results
-immediately. To make sandboxing easier this must be built w/GPU off.
-
-Running Locally
-===============
-
-$ GYP_GENERATORS=ninja  ./gyp_skia  gyp/webtry.gyp gyp/most.gyp -Dskia_gpu=0
-$ ninja -C out/Debug webtry
-$ cd experimental/webtry
-$ go build webtry.go
-$ ./webtry
-
-Then visit http://localhost:8000 in your browser.
-
-Only tested under linux, doubtful it will work on other platforms.
-
-Full Server Setup
-=================
-
-Create a GCE instance:
-
-gcutil --project=google.com:skia-buildbots addinstance skia-webtry-b \
-  --zone=us-central2-b --external_ip_address=108.170.220.126 \
-  --service_account=default \
-  --service_account_scopes="https://www.googleapis.com/auth/devstorage.full_control" \
-  --network=default --machine_type=n1-standard-1 --image=backports-debian-7-wheezy-v20140331 \
-  --persistent_boot_disk
-
-SSH into the instance:
-
-  gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-webtry-b
-
-
-The following things only need to be done once
-----------------------------------------------
-
-1. sudo apt-get install git schroot debootstrap
-2. git clone https://skia.googlesource.com/skia
-3. Add the following to /etc/fstab and reboot:
-
-  none /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0
-
-The above will allow ninja to run. See http://stackoverflow.com/questions/2009278/python-multiprocessing-permission-denied
-
-4. Add the following to the /etc/schroot/minimal/fstab:
-
-  /home/webtry/inout             /inout  none    rw,bind         0       0
-
-5. Change /etc/monit/monitrc to:
-
-  set daemon 2
-
-then run the following so it applies:
-
-  sudo /etc/init.d/monit restart
-
-This means that monit will poll every two seconds that our application is up and running.
-
-Do the following the first time you setup a machine, and each time you want to update the code running on the server
---------------------------------------------------------------------------------------------------------------------
-
-cd ~/skia/experimental/webtry/setup
-./webtry_setup.sh
-
-
-Do these steps only once, but only after running webtry_setup.sh the first time
--------------------------------------------------------------------------------
-
-1. sudo debootstrap --variant=minbase wheezy /srv/chroot/webtry
-
