# DISTNAME
|
|
# Every package definition should start with the definition of this
|
|
# variable. It is used in three places:
|
|
#
|
|
# 1. It is the first part of the default value for DISTFILES.
|
|
# 2. It is the default value for PKGNAME, except for the trailing
|
|
# "nb" part.
|
|
# 3. The default value of WRKSRC is ${WRKDIR}/${DISTNAME}.
|
|
#
|
|
|
|
# PKGNAME
|
|
# This variable is somewhat special in pkgsrc. On the one hand, it
|
|
# is intended to be defined by the package, but on the other hand,
|
|
# it is overridden by bsd.pkg.mk with a value that is similar, but
|
|
# not identical to the one provided by the package. This makes it
|
|
# somewhat tricky to use this variable correctly, because its
|
|
# value changes over time.
|
|
#
|
|
# When the variable is defined by the package, it should consist
|
|
# of the package name and version, as released upstream. The "nb"
|
|
# part is specified by another variable, PKGREVISION.
|
|
#
|
|
# Later, in bsd.pkg.mk, the "nb" part is added to PKGNAME, so when
|
|
# it is used in the package, its value may differ. The package
|
|
# name without the "nb" suffix is provided in the PKGNAME_NOREV
|
|
# variable.
|
|
#
|
|
# See also: DISTNAME, PKGREVISION, PKGNAME_NOREV.
|
|
#
|
|
|
|
# PKGREVISION
|
|
# When a pkgsrc package changes but there has not been an update
|
|
# of the upstream package, there must be a way to mark a package
|
|
# as "newer" than a previous one. That's the purpose of
|
|
# PKGREVISION.
|
|
#
|
|
# Whenever a package is modified in a user-visible way, this
|
|
# variable is increased.
|
|
#
|
|
# The value of PKGREVISION (if defined, non-empty and non-zero)
|
|
# is the last part of the PKGNAME, separated from the rest by the
|
|
# letters "nb" (which stand for NetBSD).
|
|
#
|
|
# Since this variable is specific to a single package, the only
|
|
# place where it may be defined is the package Makefile itself.
|
|
# No other file may define it.
