Yes. Both.

The easiest way is to actually look at the source code directory:
<turretarch5 303> ls $AMBERHOME/AmberTools/src/ptraj/*.c
actions.c clusterLib.c display.c experimental.c io.c netcdf_ptraj.c pubfft.c second.c trajectory.c
analyze.c correlation.c energy.c help.c main.c parallel_ptraj.c rdparm.c thermo.c utility.c
cluster.c dispatch.c evec.c interface.c mask.c ptraj.c rms.c torsion.c
Note a file there named "rms.c". Alternatively, egrep for rms and see
all the files that refer to rms...
[The core functionality is in the rms() routine in rms.c; the "action"
which controls the call, i.e. determines whether to mass weight or not,
fit, etc. is in the routine transformRMS() in actions.c.
