+# Requisites:
+# svnmerge.py has been tested with all SVN major versions since 1.1 (both
+# client and server). It is unknown if it works with previous versions.
+#
+# Differences from svnmerge.sh:
+# - More portable: tested as working in FreeBSD and OS/2.
+# - Add double-verbose mode, which shows every svn command executed (-v -v).
+# - "svnmerge avail" now only shows commits in source, not also commits in
+# other parts of the repository.
+# - Add "svnmerge block" to flag some revisions as blocked, so that
+# they will not show up anymore in the available list. Added also
+# the complementary "svnmerge unblock".
+# - "svnmerge avail" has grown two new options:
+# -B to display a list of the blocked revisions
+# -A to display both the blocked and the available revisions.
+# - Improved generated commit message to make it machine parsable even when
+# merging commits which are themselves merges.
+# - Add --force option to skip working copy check
+# - Add --record-only option to "svnmerge merge" to avoid performing
+# an actual merge, yet record that a merge happened.
+#
+# TODO:
+# - Add "svnmerge avail -R": show logs in reverse order
+#
+# Information for Hackers:
+#
+# Identifiers for branches:
+# A branch is identified in three ways within this source:
+# - as a working copy (variable name usually includes 'dir')
+# - as a fully qualified URL
+# - as a path identifier (an opaque string indicating a particular path
+# in a particular repository; variable name includes 'pathid')
+# A "target" is generally user-specified, and may be a working copy or
+# a URL.
