	* gpgme.texi (Verify): Document verification of normal and
	cleartext signatures.

gpgme/
2002-03-03  Marcus Brinkmann  <marcus@g10code.de>

	* rungpg.c (_gpgme_gpg_op_verify): If TEXT is of mode
	GPGME_DATA_MODE_IN, construct a command line that stores the
	plaintext in TEXT.
	* verify.c (gpgme_op_verify_start): Accept TEXT being
	uninitialized, and in this case interpret SIG as a normal or
	cleartext signature and TEXT as a return data object.
	* engine-gpgsm.c (_gpgme_gpgsm_op_verify): Likewise.

	* gpg/t-verify.c (main): Add a few more sanity checks, and a check
	for normal signatures.

* gpgme_op_verify now allows to pass an uninitialized data object as
its plaintext argument to check for normal and cleartext
