21 # This is a template for an options file that can be used to configure
22 # cvs2svn to convert to Mercurial rather than to Subversion. See
23 # www/cvs2git.html and www/cvs2svn.html for general information, and
24 # see the comments in this file for information about what options are
25 # available and how they can be set.
27 # "cvs2hg" is shorthand for "cvs2git in the mode where it is
28 # outputting to Mercurial instead of git". But the program that needs
29 # to be run is still called "cvs2git". Run it with the --options
30 # option, passing it this file as argument:
32 # cvs2git --options=cvs2hg-example.options
34 # Mercurial can (experimentally at this time) read git-fast-import
35 # format via its "hg fastimport" extension, with exceptions:
37 # 1. "hg fastimport" does not support blobs, so the contents of the
38 # revisions are output inline rather than in a separate blobs file.
39 # This increases the size of the output, because file contents that
40 # appear identically on multiple branches have to be output
43 # Many options do not have defaults, so it is easier to copy this file
44 # and modify what you need rather than creating a new options file
45 # from scratch. This file is in Python syntax, but you don't need to
46 # know Python to modify it. But if you *do* know Python, then you
47 # will be happy to know that you can use arbitary Python constructs to
48 # do fancy configuration tricks.
50 # But please be aware of the following:
52 # * In many places, leading whitespace is significant in Python (it is
53 # used instead of curly braces to group statements together).
54 # Therefore, if you don't know what you are doing, it is best to
55 # leave the whitespace as it is.
57 # * In normal strings, Python treats a backslash ("\") as an escape
58 # character. Therefore, if you want to specify a string that
59 # contains a backslash, you need either to escape the backslash with
60 # another backslash ("\\"), or use a "raw string", as in one if the
61 # following equivalent examples:
63 # cvs_executable = 'c:\\windows\\system32\\cvs.exe'
64 # cvs_executable = r'c:\windows\system32\cvs.exe'
66 # See http://docs.python.org/tutorial/introduction.html#strings for
69 # Two identifiers will have been defined before this file is executed,
70 # and can be used freely within this file:
72 # ctx -- a Ctx object (see cvs2svn_lib/context.py), which holds
73 # many configuration options
75 # run_options -- an instance of the GitRunOptions class (see
76 # cvs2svn_lib/git_run_options.py), which holds some variables
77 # governing how cvs2git is run
