/**
 * Copies a whole other file. Useful for "borrowing" an implementation of a simple utility from another project, without needing to publish it.
 * Obviously this creates duplicated code, so use judiciously!
 *
 * ##### basic usage
 * ```js
 * // codegen:start {preset: copy, source: ../../another-project/src/some-file.ts}
 * import {z} from 'zod'
 *
 * export const MyObject = z.object({foo: z.string()})
 * // codegen:end
 * ```
 *
 * #### excludeLines
 *
 * ```ts
 * import {z} from 'zod/v4' // in this project we use zod v4, but we're copying from a project that uses zod v3
 * // codegen:start {preset: copy, source: ../../another-project/src/some-file.ts, excludeLines: ['^import']}
 *
 * export const MyObject = z.object({foo: z.string()})
 * // codegen:end
 * ```
 *
 * #### onlyIfExists
 * ```js
 * // copy a file from a sibling project, but only if the sibling project actually exists
 * // in this case this will effectively skip the copying step on machines that don't have the sibling project installed
 * // e.g. on CI runners.
 * // codegen:start {preset: copy, source: ../../another-project/src/some-file.ts, onlyIfExists: ../../another-project/package.json}
 * import {z} from 'zod'
 *
 * export const MyObject = z.object({foo: z.string()})
 * // codegen:end
 * ```
 *
 * #### comparison
 * ```js
 * // by default, the content will perform a "simplified" comparison with existing content, so differences from tools like prettier
 * // are ignored. if you care about whitespace and similar differences, you can set the comparison option to `strict`.
 * // codegen:start {preset: copy, source: ../../another-project/src/some-file.ts, comparison: strict}
 * import {z} from 'zod'
 *
 * export const MyObject = z.object({foo: z.string()})
 * // codegen:end
 * ```
