CoFliCo : COndor FLIght track COnverter - Version 1.1.2
		compare_igc : differences between 2 IGC files

CoFliCo converts Condor flight tracks (.ftr) to IGC files
It can also rename the .ftr or .igc files according to flight parameters

Condor 1 is not supported
The conversion accuracy is very similar to the Condor converter, although some minor 
differences may show because of rounding.

No checksums are computed, hence the files produced cannot be validated.

USAGE :

CoFliCo.exe runs with a minimal GUI or in CLI (Command Line Interface) mode.
It must have access to the .trn file of the landscape in which each flight has taken place.

The input and output files may be renamed according to a user-defined scheme, see below.

The command line syntax is :

> CoFliCo [-debug] [-help] [-navicon] [-rftr] [-rigc] [-ustr:STRING] [-next|-prev|-near|-linr|-para] 
file(s)

file can be a single file, or a whitespace separated list.
* and ? can be used : (e.g. *.ftr, flight*.ftr, flight???.ftr, etc.)
if a name contains whitespaces, enclose it between ""

If no files are specified, a selection window pops-up. Multiple selections are possible

If you want to use drag-and-drop mode to start the converter, it is recommended to create 
a shortcut on your desk. It is then possible to drag file(s) to the shortcut to convert it.

all [-options] are optional, they can only be activated from the command line.

-debug : debug mode which produces a lot of printouts, use only if support needed.
-help  : prints the command line syntax

-rigc  : change output file (IGC) name according to the naming scheme
-rftr  : rename input file (.ftr) according to the naming scheme
-ustr:STRING : user-defined string to be inserted in filename(s)

-navicon : use Navicon.dll conversion (X,Y->Lat,Lon) routines (otherwise use the built-in ones)

interpolation schemes : 
-next  : next point in time (default, recommended, matches best Condor generated IGC files)
-prev  : previous point in time
-near  : nearest point in time
-linr  : linear interpolation
-para  : parabolic interpolation (most precise)

the interpolation scheme will be written at the end of the IGC file :
LCONFCOFLICOInterpolation=


Renaming files : 

The renaming scheme is defined in the CoFliCo.ini file in the installation folder
The format is built by assembling tokens and a separator (either - or _)

Valid tokens (case sensitive) are :

 Y4=year (4 digits) date and time correspond to the modification of the .ftr file
 Y2=year (2 digits)
 MM=month
 DD=day
 hh=hour
 mm=minutes
 ID=competition ID
 GL=glider type
 LA=lanscape name
 ST=Start airport
 TD=Task distance
 DF=Distance flown
 AV=Average speed
 US=user-defined string ( add -ustr:STRING in the command line)
 
The default format is Y4_MM_DD_hh_mm_ID_GL_LA_ST, any combination is valid e.g. DDMMY2_hhmm_LA 

It is also pssible to susbtitute white spaces in file names with - or _

CoFliCo will try to get the Condor installation folder from the registry. 
If this does not work it will be read from CoFliCo.ini in the installation folder 
(update the value of "Condor 2 Path")

------------------

compare_igc allows to compare 2 IGC files and displays min,average and max differences

it was designed to allow to compare different conversions from the same flight track

it works only in command line mode

USAGE : 

> compare_igc file1.igc file2.igc 

If the files do not have the same number of fixes, the bigger one should be second on the command line
