hspace in cm?

[Xavier Scheuer]

Hi dear lily users!

I'd like to know if it is possible, inside a markup, to make a
horizontal space with a value _in centimeters_ (and not in
"staff-spaces")?

Actually, I'd like to make a horizontal space of the value of "indent".
So it would be even better if we could "get" the value stored in
"indent" (within the \paper block) and make a hspace of this value
*automatically*.

Could somebody help me with this?

Many thanks in advance,
Xavier
