Package shlex implements a simple lexer which splits input in to tokens using
shell-style rules for quoting and commenting.
The basic use case uses the default ASCII lexer to split a string into sub-strings:
shlex.Split("one \"two three\" four") -> []string{"one", "two three", "four"}
To process a stream of strings:
l := NewLexer(os.Stdin)
for ; token, err := l.Next(); err != nil {
// process token
}
To access the raw token stream (which includes tokens for comments):
t := NewTokenizer(os.Stdin)
for ; token, err := t.Next(); err != nil {
// process token
}

Simple byte size formatting.
This package implements types that can be used in stdlib formatting functions
like `fmt.Printf` to control the output of the expected printed string.
Floating point flags %f and %g print the value in using the correct unit
suffix. Decimal units are default, # switches to binary units. If a value is
best represented as full bytes, integer bytes are printed instead.
Examples:
fmt.Printf("%.2f", 123 * B) => "123B"
fmt.Printf("%.2f", 1234 * B) => "1.23kB"
fmt.Printf("%g", 1200 * B) => "1.2kB"
fmt.Printf("%#g", 1024 * B) => "1KiB"
Integer flag %d always prints the value in bytes. # flag adds an unit prefix.
Examples:
fmt.Printf("%d", 1234 * B) => "1234"
fmt.Printf("%#d", 1234 * B) => "1234B"

#### Simple byte size formatting.
This package implements types that can be used in stdlib formatting functions
like `fmt.Printf` to control the output of the expected printed string.
Floating point flags `%f` and %g print the value in using the correct unit
suffix. Decimal units are default, `#` switches to binary units. If a value is
best represented as full bytes, integer bytes are printed instead.
##### Examples:
```
fmt.Printf("%.2f", 123 * B) => "123B"
fmt.Printf("%.2f", 1234 * B) => "1.23kB"
fmt.Printf("%g", 1200 * B) => "1.2kB"
fmt.Printf("%#g", 1024 * B) => "1KiB"
```
Integer flag `%d` always prints the value in bytes. `#` flag adds an unit prefix.
##### Examples:
```
fmt.Printf("%d", 1234 * B) => "1234"
fmt.Printf("%#d", 1234 * B) => "1234B"
```
`%v` is equal to `%g`
