[Type] is a buffer type that can take one of the following values: Q (constant Q), I (constant increment), B (Bragg).
[N] is a number given to a buffer of interest. Alternatively, the user can use from and to numbers to specify a range of buffers to be run.
[Operation] is a list of value assignments in the form [Field1]=[Value1],[Field2]=[Value2],... The following buffer fields can be recognized:

For example, BUFOP Q1-10 T=200 will change the temperature parameter in the first ten Q-buffers to 200K. BUFOP Q1-10 A=VLAT,B=VLAT will change lattice parameters A and B to the current value of the variable VLAT in the first ten Q-buffers.
