This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
Its main focus is on cards that support cryptographic operations, and
facilitate their use in security applications such as mail encryption,
authentication, and digital signature. OpenSC implements the PKCS#11 API
so applications supporting this API such as Mozilla Firefox and Thunderbird
can use it. OpenSC implements the PKCS#15 standard and aims to be compatible
with every software that does so, too.
