several checks on the code's behavior are made in 
CheckSanity.c

NDEBUG is set when debugging is turned off, and is 
undefined when the debug version is built
#if !defined(NDEBUG)
	ChkSumCon(0);
#endif

pclint - command line points to std.lnt, which points to 
co-msc60.lnt (ms vs c compiler)
options.lnt (my options)

edit options.lnt to change user options, like which routines do not return 

pc lint tool
command: c:\u\lint8\lint-nt.exe
arguments -i"c:\u\lint8" -u std.lnt env-vc6.lnt $(FilePath) <= vc6
arguments -i"c:\u\lint8" -i"c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include" -u std.lnt env-vc7.lnt $(ItemPath) <= vc7
arguments -i"c:\u\lint8" -i"C:\Program Files\Microsoft Visual Studio 8\VC\include" -u std.lnt env-vc7.lnt $(ItemPath) <= vc8

initial directory $(FileDir) <= vc6
initial directory $(ItemDir) <= vc7
check "use output window"

entire project, same except
arguments -i"c:\u\lint8" -i"c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include" -u std.lnt env-vc7.lnt project.lnt
arguments -i"c:\u\lint8" -i"C:\Program Files\Microsoft Visual Studio 8\VC\include" -u std.lnt env-vc7.lnt project.lnt <= vc8

to test entire project, must have list of all files in project in file project.lnt, 
to do this cd to source dir and do
ls *.c > project.lnt

pc lint options:
-passes(2) or -passes[2] do two passes on the source (section 9.2.2)
-function( exit, cdEXIT ) cdEXIT exits, section 10.1, Function Mimicry (-function)

unit integration checks:
there are currently two.  The emission line array is tested in routine LineSet1
where a fake emission line with local emissivty 1e-10, label "Unit", wavelength 1,
is passed through the lines arrays.   It is then checked at the end of the calculation
in routine PrtFinal.

a similar test is done with the continuum transfer arrays.  the continuum is actually
defined wth rfield.nflux points, the loops are always up to < rfield.nflux.  In metdif
the local emissivty at [rfield.nflux] is set to 1e-10f, and then passed through the
continuum transfer arrays.  This is also checked in PrtFinal.

the number is actually 1e-10 so that it does not overflow on 32-bit machines.

==================================================================
/* following routine provides a debugging hook into the main line array 
 * loops over whole array and finds every line that matches length,

pclint 

single file "arguments" -i"C:\U\PCLINT" -u std.lnt env-vc6.lnt $(FilePath)

project
	Command:            C:\LINT\LINT-NT.EXE
    Arguments           -i"C:\LINT" std.lnt env-vc6.lnt project.lnt
	Initial Directory   $(FileDir)

    This will require that the file that you are currently editing reside
    in a directory that contains a file called 'project.lnt'.
	ls *.c >project.lnt
