Read from PORT an OpenPGP keyring in binary format; return a keyring based on all the OpenPGP primary keys that were read. The returned keyring complements KEYRING. LIMIT is the maximum number of keys to read, or -1 if there is no limit.

Return two values: the first key with ID in KEYRING, and a list of associated packets (user IDs, signatures, etc.). Return #f and the empty list of ID was not found. ID must be the 64-bit key ID of the key, an integer.

Read from PORT an ASCII-armored detached signature. Return an <openpgp-signature> record or the end-of-file object. Raise an error if the data read from PORT does is invalid or does not correspond to a detached signature.

Read STR, an ASCII-armored OpenPGP packet, and return the corresponding OpenPGP record.

Return a string representing BV, a bytevector, in the conventional OpenPGP hexadecimal format for fingerprints.

Return the transitive target inputs of PACKAGE---i.e., its direct inputs along with their propagated inputs, recursively. This only includes inputs for the target system, and not native inputs.

Same as 'package-direct-inputs', but applied to a bag.

Like 'package-location', but return the location of the definition itself--i.e., that of the enclosing 'define-public' form, if any, or #f.

Return a procedure that, when passed a package, replaces its direct and indirect dependencies, including implicit inputs when DEEP? is true, according to REPLACEMENTS. REPLACEMENTS is a list of package pairs; the first element of each pair is the package to replace, and the second one is the replacement.

When RECURSIVE? is true, apply replacements to the right-hand sides of REPLACEMENTS as well, recursively.

Optionally, REWRITE-NAME is a one-argument procedure that takes the name of a package and returns its new name after rewrite.
