svnexternals: preliminary support for subrepos based externals At this point, only pulling externals definitions into .hgsub and .hgsubstate is supported. One difference between subrepos and svn:externals is the former separate the source definition and target revision in two files, while svn:externals definitions contain both. To handle this, the svn:externals revision references is replaced with a {REV} placeholder and stored in .hgsub, prefixed with the external base directory separated with a ':', while the revision is extracted in .hgsubstate. For instance, the following external: -r3 ^/externals/proj2@2 deps/proj2 Becomes: (.hgsub) deps/proj2 = [hgsubversion] :-r{REV} ^/externals/proj2@2 deps/proj2 (.hgsubstate) 3 deps/proj2
