[evla-sw-discuss] Re: Software sizes

Just for another comparison I've attached a line count done for the VLT
about a year ago.  These guys are definitely "heavyweights" and
demonstrate what can be done given enough resources.

The interesting number is 2.4 million lines (or about 160 FTE's) for the
"common software", telescope and instrument control.

included you find an estimate of the lines of code for the VLT project.
The measure does not include comment or empty lines.

The tool I used is called sloccount, publicly available.

The list is separated between "VLT" part:
- VLT common software
- Telescope Control System
- Instrument software 

and the Dataflow  ("DMD") part:
- Exposure Time calculators 
- Phase 1 and phase 2 proposal handling
- On Line reduction pipeline
- Midas reduction system 
- Archival system

Both contain probably much more than that, but I do not know all the
details.

For the VLT, I have an estimate of 250 man-year.
