### The directory environment:

VDRDIR = ../../..
LIBDIR = ../../lib
TMPDIR = /tmp

# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.
#
PLUGIN  = mp3
PLUGIN2 = mplayer

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config
-include Make.config

### The version number of this plugin:

HGARCHIVE = .hg_archival.txt
RELEASE := $(shell grep 'define PLUGIN_RELEASE' version.h | awk '{ print $$3 }' | sed -e 's/[";]//g')
RELSTR  := $(shell if test -d .hg; then \
                     echo -n "-"; (hg identify 2>/dev/null || echo -n "Unknown") | sed -e 's/ .*//'; \
                   elif test -r $(HGARCHIVE); then \
                     echo -n "-"; grep "^node" $(HGARCHIVE) | awk '{ printf "%.12s",$$2 }'; \
                   fi)
VERSION := $(RELEASE)$(RELSTR)

### The version number of VDR (taken from VDR's "config.h"):

VDRVERSION := $(shell sed -ne '/define VDRVERSION/ s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/include/vdr/config.h)
APIVERSION := $(shell sed -ne '/define APIVERSION/ s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/include/vdr/config.h)

### The name of the distribution archive:

ARCHIVE = $(PLUGIN)-$(RELEASE)
PACKAGE = vdr-$(ARCHIVE)
