New virtual class for manipulating cryptographic message syntax messages

2001-05-31  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-cms-context.[c,h]: New virtual class for manipulating
	cryptographic message syntax messages (like S/MIME).

	* camel-smime-context.[c,h]: Modified to inherit from the
	CamelCMSContext class rather than the CamelCipherContext class.

	* camel-smime.[c,h]: Removed - just use camel-smime-context
	directly.

	* camel-smime-utils.[c,h]: New source files. Moved the 2 useful
	functions from camel-smime.[c,h] into here.
