Getting Started
===============

use "-h" option to get started.

Running Examples:

1. run as a single daemon

  memcachedb -p21201 -d -r -u root -H ./env -N -v

2. run as a replicated group (i do this.)

  start a master (read&write):

    memcachedb -p21201 -d -r -u root -H ./env1 -N -R 127.0.0.1:31201 -M

  then, start a replcas (read-only):

    memcachedb -p21202 -d -r -u root -H ./env2 -N -R 127.0.0.1:31202 -O 127.0.0.1:31201 -S

Have fun :)
