## -- ESVN_STORE_DIR:  subversion sources store directory

## -- ESVN_FETCH_CMD:  subversion fetch command
#
ESVN_FETCH_CMD="svn checkout"

## -- ESVN_UPDATE_CMD:  subversion update command
#
ESVN_UPDATE_CMD="svn update"


## -- ESVN_OPTIONS:
#
# the options passed to checkout or update.
#
: ESVN_OPTIONS=${ESVN_OPTIONS:=}


## -- ESVN_REPO_URI:  repository uri
#
# e.g. http://foo/trunk, svn://bar/trunk
#
# supported protocols:
#   http://
#   https://
#   svn://
#   svn+ssh://
#
: ESVN_REPO_URI=${ESVN_REPO_URI:=}


## -- ESVN_PROJECT:  project name of your ebuild (= name space)
#
# subversion eclass will check out the subversion repository like:
#
#   ${ESVN_STORE_DIR}/${ESVN_PROJECT}/${ESVN_REPO_URI##*/}
#
# so if you define ESVN_REPO_URI as http://svn.collab.net/repo/svn/trunk or
# http://svn.collab.net/repo/svn/trunk/. and PN is subversion-svn.
# it will check out like:
#
#   ${ESVN_STORE_DIR}/subversion/trunk
#
# this is not used in order to declare the name of the upstream project.
# so that you can declare this like:
#
#   # jakarta commons-loggin
#   ESVN_PROJECT=commons/logging
#
# default: ${PN/-svn}.

# bootstrap script or command like autogen.sh or etc..

## -- ESVN_PATCHES:
#
# subversion eclass can apply pathces in subversion_bootstrap().
# you can use regexp in this valiable like *.diff or *.patch or etc.
# NOTE: this patches will apply before eval ESVN_BOOTSTRAP.
#
# the process of applying the patch is:
#   1. just epatch it, if the patch exists in the path.
#   2. scan it under FILESDIR and epatch it, if the patch exists in FILESDIR.
#   3. die.
