This may solve the #104 ?
or consider including this all fossasia/meilix-generator#79 (comment)

[xeon-zolt]

No, it does not solves #104
I have not tested it for user name change so not including last two lines

[abishekvashok]

It doesnot add hotelos user but an user from the travis tag right?

@zeon-zolt As this whole PR is just two lines of code, does this mean you retract the two lines of code and seek a different solution?

[tabesin]

The PR naming "this for" is a bit unclear, please improve.
