.Sh DESCRIPTION
When you set the 'svn:eol-style' property on a file in a Subversion repository,
.Xr svn 1
checks the line endings in that file for consistency. If the newlines are
inconsistent -- i.e., they are a mixture of Windows ('\er\en'), legacy Macintosh
('\er'), and/or Unix ('\en') newlines -- then an error is raised and the propset
fails. The file can still be forced into the repository, but then you have
broken data in your repo.

The solution is to clean up the newlines in your text files before trying to
commit them. This can be done for single files with a utility such as
.Xr dos2unix 1 .
.Nm
is a
.Xr python 1
program that makes the job easier for a whole tree of files.

.Nm
walks the tree rooted at
.Ar path
(which defaults to the current working directory) and does one of three things,
depending on
.Ar subcommand :
.Bl -hang -offset indent
.\"
.\"
.It Nm clean
cleans up the line endings in all text files
.\"
.\"
.It Nm confgen
prints a minimal
.Xr svn 1
configuration file with all file extensions and filenames without an extension
in an auto-props section, setting 'svn:eol-style' to 'native'.
.\"
.\"
.It Nm find
prints the paths of all text files
.El
.Pp

For
.Nm clean
and
.Nm find ,
the definition of a text file
is taken from the current user's
.Xr svn 1
configuration file, which is assumed to be at:
.\"
.\"
.Bd -literal -offset indent
.Pa ~/.subversion/config
.Ed
.Pp

Text files are those with filenames matching any
.Xr glob 1
in the [auto-props]
section for which the 'svn:eol-style' property is set. All Windows newlines in
these files are converted to Unix newlines. We don't deal with legacy Macintosh
newlines, since
.Xr svn 1
only runs on versions of Mac OS that use the Unix convention.

Note that
.Ar path
does not have to be an
.Xr svn 1
working copy. In fact,
.Nm svneol Ns 's
primary use case is preparing a large, non-versioned tree for initial import
into a Subversion repository.
