[lammps-users] Is there any manual for 'compute sum' command

Dear all,

I saw in some input script that ‘compute sum’ command was used. But in the part of ‘Recent LAMMPS News’ shown in the homepage of Lammps, the weblink to this command is unavailable. Moreover, there is also no information of this command is in the subsection of the “Compute” command . Why?

It's now the compute reduce command - sum is one option.
