#
# This Makefile fragment is included by bsd.pkg.mk and encapsulates the
# code to produce README.html files in each package directory.
#
# The following are the "public" targets provided by this module.
#
#    readme		This target generates a README.html file suitable
#			for being served via FTP.
#
#    cdrom-readme	This target generates a README.html file suitable
#			for being served from a mounted CD-ROM.
#
# The following are the user-settable variables that may be defined in
# /etc/mk.conf.
#
#    FTP_PKG_URL_HOST is the host portion of the URL to embed in each
#	README.html file to be served via FTP, and defaults to
#	"ftp://ftp.NetBSD.org".
#
#    FTP_PKG_URL_DIR is the directory portion of the URL to embed in each
#	README.html file to be served via FTP, and defaults to
#	"/pub/pkgsrc/packages".
#
#    CDROM_PKG_URL_HOST is the host portion of the URL to embed in each
#	README.html file to be served from a mounted CD-ROM, and defaults
#	to "file://localhost".
#
#    CDROM_PKG_URL_DIR is the directory portion of the URL to embed in each
#	README.html file to be served from a mounted CD-ROM, and defaults
#	to "/usr/pkgsrc/packages".
#

# Set to "html" by the README.html target to generate HTML code,
# or to "svr4" to print SVR4 (Solaris, ...) short package names, from
# SVR4_PKGNAME variable.
# This variable is passed down via build-depends-list and run-depends-list
