branch: master
commit 85a5ad676ad756ac1398f470f2dc007d06c4462c

    zeropoint: using single equal instead of the double for checking
    
    Until now, in checking the '--keepzpap', we used the double equal sign
    ('=='), which can cause errors in some shells. Because they intterpret it
    as pattern matching.
    
    With this commit, this problem is fixed by using the single equal sign.
