//! Read and write PowerWorld auxiliary `.aux` files.
//!
//! The reader is layered. [`parse_aux`] parses any auxiliary file into the
//! generic [`AuxFile`] — every `DATA` and `SCRIPT` section, with field lists,
//! value rows, and `SUBDATA` blocks intact — and knows the grammar from the
//! official format guide: legacy and concise headers, comma delimited (CSV)
//! sections, multiline field lists and value rows, `//` comments, quoting,
//! and `variablename:location` field suffixes. On top of it, the [`Network`]
//! mapping consumes the power flow core types (Bus, Load, Shunt, Gen,
//! Branch) by field name, so column order and extra columns don't matter.
//! Object types outside the core stay reachable through [`aux_sections`] and
//! survive the same format round trip byte for byte via the retained source
//! (see [`crate::write_as`]).
//!
//! The writer emits `DATA (Object, [fields]) { … }` blocks for the core
//! types, values in MW/MVAr/degrees, status as `Closed`/`Open`. Generator
//! cost, HVDC, and storage are not represented and are reported on write.
//!
//! `.pwb` binary cases are read (never written) by [`parse_pwb`]; see that
//! module for the decoded vintages and the parity evidence. `.pwd` display
//! files carry no case data, only the diagram; [`parse_pwd_file`] and
//! [`parse_pwd`] read the decoded substation coordinates.
//!
//! [`Network`]: crate::network::Network
