If an encoding is declared, the encoding name must be recognized by Python. The encoding is used for all lexical analysis, in particular to find the end of a string, and to interpret the contents of Unicode literals. String literals are converted to Unicode for syntactical analysis, then conv...

Binary files are buffered in fixed-size chunks; the size of the buffer is chosen using a heuristic trying to determine the underlying device’s “block size” and falling back on io.DEFAULT_BUFFER_SIZE. On many systems, the buffer will typically be 4096 or 8192 bytes long. “Interactive”...

Any fatal errors within jc will generate an exit code of 100, otherwise the exit code will be 0.When using the "magic" syntax (e.g. jc ifconfig eth0), jc will store the exit code of the program being parsed and add it to the jc exit code. This way it is easier to determine ...
