[QE-users] About the rules for skipping the comment in the script cif2qe.sh.

[Hongyi Zhao]

Hi,

In the script cif2qe.sh, it uses the following rules to skip the
comment of the CIF file:

$1 ~ /^\#/||/^\;/ { next }

See <https://gitlab.com/QEF/q-e/-/blob/develop/PW/tools/cif2qe.sh#L250>
for more info.

But I can't figure out why should it use this rule for the lines
beginning with ';'. According to the description on the iucr's website
<https://www.iucr.org/resources/cif/spec/version1.1/cifsyntax>, the
following note is given:

; at beginning of line of text delimits non-simple data values

It doesn't identify comment, so really should we skip the corresponding line?

Regards,
