Polyblock works in two modes: the embedded mode, where the block syntax is embedded in a language's syntax, and the standalone mode, where the file is encoded primarily with the Polyblock syntax.

In standalone mode, the parsing is done line by line, using indentation to determine where the content belongs:

• Block declarations all start with an unindented @ followed by the block name and some optional data.
• Block content all start with an indented value (by default, one tab).
• Comments are unindented and start with a #.

In embedded mode, the parsing is also done on a line-by-line basis, with the following differences:

• Block declarations all start with a customizable language-specific prefix (# for shell-like, * for C-Like languages) followed by the @, like in the standalone mode.
• Block content must follow directly after the block declaration.
• Host language code is included as a verbatim block.
