Strings delimited by “” are compressed strings. This means they are ASCII strings converted from base 96 or under (the 95 printables and newline) to base 255 (the full 8-bit codepage minus ”). The first character in the string is the encoded character for the base.
Strings delimited by ”” are permuted compressed strings. This means they are ASCII strings converted from base 96 or under to base 255. The first character in the string is the encoded index of the permutation number, the second is the encoded character for the base.
The default order of the ASCII character set is whitespace, symbols, lowercase letters, numbers, and uppercase letters. An index is generated based on the number of uses of each type of character using this order as the base.
Pretty simple. In succinct mode it's just <command><arguments>, in verbose mode it's just <command>(<arguments>).
