Did the poap.py.md5 file necessary for the POAP process?

[aoterbear]

I am confused about if the poap.py.md5 file is necessary for the POAP process? And if it's necessary, what's the content should be? Should it be only one line like this below?
######################################################
the MD5 value calculated with command md5sum poap.py poap.py
######################################################
And I know the second line which contains the MD5 value in the poap.py file need to be updated once the file is changed, so the value in the poap.py file second line must be not same with the output of md5sum poap.py command. According to Cisco docs, the nexus switch need to check the MD5 hash value of the poap.py file, and every file in the POAP process need a corresponding .md5 extension file, so which one the nexus switch will choose to use for the mMD5value compare?
