code:根据提供的参数提取信息 do.py mod test.cnf

能够根据mod输出mod中的配置信息。如：do.py mod3 test.cnf, output is :

key="name1"
file="test"

---------------------------

file: test.cnf
[mod1]
JAVA_ARGS="-server -Xms512m -Xmx512m -XX:NewSize=64m -XX:+UseConcMarkSweepGC"

JAVA_OPTSS="${JAVA_ARGS} -Dsun.rmi.dgc.server.gcInterval=3600000"

[mod2]
key="name"
JAVA_ARGS="${JAVA_ARGS} -Dsun.rmi.dgc.client.gcInterval=30000"

[mod3]
key="name1"
file="test"
