-
-```typescript
-import fs from 'fs'
-import VCF from '@gmod/vcf'
-import { createGunzip } from 'zlib'
-import readline from 'readline'
-
-const rl = readline.createInterface({

-## Constructor
-
-```typescript
-new VCF({ header: string, strict?: boolean })
-```
-
-- `header` — the full VCF header string (LF or CRLF)
-- `strict` — throw on missing INFO field (default `true`)
-
 ## Variant
 
 `parseLine(line)` returns a `Variant` with these fields:
