my $text = slurp($file);
```

Reads and returns the full contents of a file using `IO::File`. On failure,
calls `err`.

### blurp

```perl
blurp($file, $text);
```

Writes text to a file, replacing any existing content. Open, write, and close
failures call `err`.

### touch

```perl
touch($file);
```

Ensures a file exists. If the file is missing, creates it as an empty file.

### arg

```perl
my $param = arg(@args);
```

Parses the fixed argument sequence passed by generated make targets into a hash
reference. The recognized fields are:

- `NAME`
- `NAME_SYM`
- `DISTNAME`
- `DISTVNAME`
- `VERSION`
- `VERSION_SYM`
- `VERSION_FROM`
- `LICENSE`
- `AUTHOR`
- `TO_INST_PM`
- `EXE_FILES`
- `DIST_DEFAULT_TARGET`
- `SUFFIX`
- `ABSTRACT_FROM`

Any remaining values are stored in `ARGV_AR`.

The helper also derives:

- `TO_INST_PM_AR` from whitespace-splitting `TO_INST_PM`
- `EXE_FILES_AR` from whitespace-splitting `EXE_FILES`

### perlrun

```perl
my $command = perlrun($hook_object, $make_maker_object);
```

Builds the global Makefile `PERLRUN` command beginning with `$(PERL)`. It
includes non-default local `@INC` directories as `-I` options, loaded
`ExtUtils::*` modules as `-M` options, and the registered MakeMaker extension
classes in activation order. Modules are emitted once. When supplied, the
active MakeMaker object quotes `-I` arguments for the platform shell.

This value is installed into MakeMaker's `PERLRUN` macro by
`ASPEER::MakeMaker::MM::Import::const_config` and is reused by generated
targets.

## Usage Conventions

Functions in this module are intended for build-time helper code and generated
make target methods. New make target methods should use `arg` to decode their
calling arguments instead of reading positional values directly.
