def Lake.stringToLegalOrSimpleName (s : String) : Lake.Name

  Defaults to false.

  The directory containing the package's Lean source files. Defaults to the package's directory.

  (This will be passed to lean as the -R option.)

• releaseRepo? : Option String

  The URL of the GitHub repository to upload and download releases of this package. If none (the default), for downloads, Lake uses the URL the package was download from (if it is a dependency) and for uploads, uses gh's default.

• releaseRepo : Option String

  The URL of the GitHub repository to upload and download releases of this package. If none (the default), for downloads, Lake uses the URL the package was download from (if it is a dependency) and for uploads, uses gh's default.

• buildArchive? : Option String

  A custom name for the build archive for the GitHub cloud release. If none (the default), Lake uses buildArchive, which defaults to {(pkg-)name}-{System.Platform.target}.tar.gz.

• buildArchive : String

  A custom name for the build archive for the GitHub cloud release. Defaults to {(pkg-)name}-{System.Platform.target}.tar.gz.

• preferReleaseBuild : Bool

  Whether to prefer downloading a prebuilt release (from GitHub) rather than building this package from the source when this package is used as a dependency.
