"Make Input ICC" is a small wrapper around Argyll CMS http://www.argyllcms.com/ for creating input (camera) profiles and performing basic checks on those. It is intended for profiling over raw data using RawDigger to obtain information necessary to calculate profiles.
No installation is needed, just unzip it to a folder of your choice and run the application.

CIED file (reference data) contains spectral, XYZ, or Lab data measured from the target you are shooting using a spectrophotometer. Some batch-measured CIED files (including spectral data for various colorcheckers) are in the ReferenceData folder. Choose ColorCheckerSG_spectral.cie if you will be running sample DevD files from the Work folder in the distribution.
DevD file (device data) contains RGB values obtained from the shot of the target. Two DevD files for ColorChecker SG card are in the Work folder. The tool I used to make DevD files is RawDigger http://www.rawdigger.com - it takes a raw file as input and allows to obtain DevD file through Selection Grid and/or manual patch sampling, see http://www.rawdigger.com/usermanual/selection-grid and http://www.dpreview.com/forums/post/51015916 on the use of flat field feature). You can also use Danny Pascale's PatchTool http://www.babelcolor.com/index.htm#PatchTool for the purpose of extracting Dev data from a tiff file.
You can use buttons to open CIED and DevD files, or drag them into respective fields.
If you will be running the sample DevD file with gamma 1, NIKON_D4_Z100_4prof_NEF_g1_max227.txt, you can start with setting algorithm to matrix only. For gamma 2.2 file, NIKON_D4_Z100_4prof_NEF_g22_max242.txt, a good start is gamma + matrix algorithm. You can try using auto scale white point and compare results.
Argyll utilities are in Argyll_bin_Mac or Argyll_bin_Mac depending on the platform. They are current, and you can replace them with a different version if needed. No installation is necessary.
The resulting profile, ti3 file, neutrality and deltaE2000 reports (and optionally, log) are going to Work folder by default. Generally files go to the folder where the DevD file resides. Reports are saved in csv format and you can open them with some spreadsheet software for analysis.
Profile neutrality report is displayed as a plot.
delatE2000 report is displayed as a table, you can sort it by pressing the column name. Obviously, the sorting by error (deltaE2000 column) is the most often case.
Resulting profile has ti3 data embedded, with some fields added to ti3 to know what parameters were used while profiling.
In my profiling experience it is convenient to put camera serial number and lens type into Description field.
Any complaints and suggestions are most welcome. If the wrapper emits an error please save the log and e-mail it to me.
(*) Contrary to common practice I suggest you start not from the default cLUT profile algorithm but with some matrix algorithm. Neutrality report will tell you one of the reasons why.
(**) Try all algorithms here and see the difference in your raw converter.
(***) The RGB curves on Neutrality report should closely follow each other and they need to be pretty smooth.
(****) If your max. deltaE2000 is below 6 you are in excellent shape.
