If name is the name of a Mathematica context, ending with a ` context mark character, then Get will process this name to find the file to read.
If name is the name of a file, any .m extension must be included explicitly.
Get can read .mx files of Mathematica definitions written by DumpSave.
Get can read .nb notebook files, returning the Mathematica expressions they represent.
<<"name" is equivalent to <<name. The double quotes can be omitted if the name is of the form specified in "Operator Input Forms".
If a file with name file.mx is found to be a directory, Get will look for a file with a name like file.mx/$SystemID/file.mx.
If the file found by <<name is a directory, Mathematica will try to load the file init.m in that directory.
Get by default successively searches for files in the directories specified by the elements of $Path.
Get[name, Path->{"dir1", "dir2", ...}] successively searches for files in each of the diri.
Syntax errors in Mathematica input files are reported in the standard form: filename: line: syntax error in expr. Get continues attempting to read a file even after a syntax error has been detected. However, if an error is detected, $Context and $ContextPath are reset to the values they had when Get was called.
During the execution of Get, the global variable $Input is set to the name of the file being read.
Get["file", "key"] reads a file which has been encoded using Encode["source", "file", "key"].
