'''Purpose:''' .



=== Requires  ===
 * [[LMRKLIST.TXT]] - Full list of landmarks.
 * LIST.TXT - Temporary list of the subset of landmarks which the user wishes to process, for sorting and removal of duplicates using the program duplicates.
 * [[LMKFILES]] - Directory containing all the LMKFILES listed in LMRKLIST.TXT and LIST.TXT.
 * [[MAPFILES]] - Directory containing all the MAPFILES for landmarks listed in LMRKLIST.TXT and LIST.TXT.

=== Output ===
 * make_script.in - .in file required by [[make_scriptP]] for generating the run scripts required to iterate the landmarks using [[lithosP]]. 

== Using duplicates ==

duplicates processes landmark names as follows:
 * for every landmark listed in [[LMRKLIST.TXT]]:
  * duplicates checks that the MAPFILE exists;
  * duplicates obtains the maplet's Q-size and Ground Sample Distance (GSD) from the LMKFILE;
  * duplicates sorts the list by decreasing GSD and increasing name (lat/wlong identifier and numeric identifier);
  * duplicates discards duplicate entries;
 * for every landmark listed in LIST.TXT:
  * duplicates checks that the landmark is also listed in [[LMRKLIST.TXT]], if so the landmark is included in the output;
 * duplicates writes the sub-set of ordered landmarks to make_script.in.

NB:
 * The LANDMARK and MAP files for the landmarks included in [[LMRKLIST.TXT]] must exist in [[LMKFILES]]/ and [[MAPFILES]]/;
 * duplicates only considers landmarks contained in LIST.TXT, that are also contained in [[LMRKLIST.TXT]].
