// This class checks a number of ARC/INFO AAT files, making sure that no
// pair of connected arcs have a different value for ELEV.
// The results are written to stanard err.
// It calls class Arccheck.java
// The optinal first argument is the search directory.
// The optional second argument is a string with which the coverage name begins
// The default values are  . and con, i.e. this will check every cover beginning
// with the characters "con" in the current directory.
// More precisely, it checks every aat.adf subdirectory of every directory
// beginning with the specified characters.
// Caveats:
//  Error handling is neither complete nor elegant
//  This class and class Arccheck assume a unix style "/" separator, which is
//  probably not portable.
//  This will recognize AAT files which are not stored as "aat.adf".
//  Class Arccheck assumes a specific item list for the arcs being checked.
//  This includes an 8-byte length, i.e. it assumes double precision.
//  This was compiled and checked under JDK Beta3 under Solaris.
