#
# == NAME
# gforge.sh - for Frugalware
#
# == SYNOPSIS
# Common schema for packages hosted on a Gforge based repository.
#
# == EXAMPLE
# --------------------------------------------------
# pkgname=ecm
# pkgver=6.2.1
# pkgrel=1
# pkgdesc="Elliptic Curve Method for Integer Factorization"
# depends=('gmp')
# groups=('apps-extra')
# archs=('i686')
# sha1sums=('bb08c4f1b412110ef64572c387baa5bc45ae8a60')
# _F_gforge_repo="http://gforge.inria.fr"
# Finclude gforge
# --------------------------------------------------
#
# == OPTIONS
# * _F_gforge_name ( defaults to $pkgname)
# * _F_gforge_repo (defaults to http://gforge.org): the gforge repository
# to use
# * _F_gforge_dirname (default to $pkgname): if the source
# tarball uses a name different to the gforge project name, then use this
# option to declare the project name
# * _F_gforge_ext (defaults to .tar.gz): extension of the source tarball
# * _F_gforge_pkgver ( defaults to $pkgver ) : Some packages are called foo-1.2.3
# * _F_gforge_sep ( defaults to - ): used for source() and up2date. As example
# for an "bar_1.2.3.tar.gz" tarball you should use _F_gforge_sep="_" , for empty
# values use _F_gforge_sep="None" that way you can dowload such foo1234.tgz
# but the source is called different from $pkgver , e.g: foo-123 , foo-12.3 , in such
# a case _F_gforge_pkgver may help to avoid custom $source
# * _F_gforge_id ( defaults autodetect ) : In case of audetection failed
