Add FILE to DIRECTORY under NAME, and return the resulting directory. DIRECTORY and FILE must be hashes identifying objects in the IPFS store.

Add FILE under NAME to the IPFS and return a content object for it.

Return a content object for an empty directory.

Publish OBJECT under the current peer ID.

Return an input port to read the content of OBJECT from.

Add DATA, a bytevector, to IPFS. Return a content object representing it.

Return a wrapper of PROGRAM that executes it with the least authority.

PROGRAM is executed in separate namespaces according to NAMESPACES, a list of symbols; it runs with GUEST-UID and GUEST-GID. MAPPINGS is a list of <file-system-mapping> records indicating directories mirrored inside the execution environment of PROGRAM. DIRECTORY is the working directory of the wrapped process. Each environment listed in PRESERVED-ENVIRONMENT-VARIABLES is preserved; other environment variables are erased.

When USER and GROUP are set and NAMESPACES does not include 'user, change UIDs and GIDs to these prior to executing PROGRAM. This usually requires that the resulting wrapper be executed as root so it can call setgid(2) and setuid(2).

Return a lax, permissive, non-copyleft license (for example a variant of the 3-clause BSD license or the Expat license), whose full text can be found at URI, which may be a file:// URI pointing the package's tree.
