These programs may be organized thematically into broad categories performing different tasks: construct initial conditions, run simulations, analyze and visuialize simulation results, etc. In practice the categories below are somewhat narrower, reflecting the fact that two different data structures are widely used in these programs. A snapshot is used to represent a configuration of bodies in phase-space; in addition to positions and velocities, snapshots may also contain other information. A general spherical profile is used to represent a spherical density profile.
With a few exceptions, the name of a program indicates the kind of data it operates on. The simulation programs all have names ending in the word code; suffixes may be appended to indicate variations. Routines which create general spherical profiles have names ending with the initials gsp, while those which operate on general spherical profiles have names starting with gsp. Likewise, routines which create snapshots usually have names ending with the word snap, while those which operate on snapshots have names starting with snap. (By this logic, routines which construct snapshots from general spherical profiles should have names starting with gsp and ending in snap, but this seemed too wordy; the ending snap is omitted.) Finally, a handfull of programs which operate on any structured file of data have three-letter names ending with the initials sf.
