.Sh DESCRIPTION
.Nm
is a client to http://paste.xinu.at which allows the user to easily upload,
delete or download files.
By default, files will be uploaded as-is and a link to the file will be printed
to stdout after each upload.
.Pp
Directories will be packed into a tarball with
.Xr tar 1 and the resulting
.Pa upload.tar
file will be uploaded.
If no arguments are given, data will be read from stdin into a temporary file
that will be uploaded as soon as EOF is received.
If the file being uploaded is bigger than 10MB
.Nm
will query the server for the maximum upload size and abort the upload if the
file would be rejected.
Before terminating,
.Nm
will try to copy all links into the X clipboard if
.Xr xclip 1
is installed.
.Pp
If you want to use paste.xinu.at, you need to create an account there and add the following to your
.Pa ~/.netrc :
.Pp
.Bd -literal -offset indent
machine paste.xinu.at
  login <your_username> password <your_secret_password>

.Sh OPTIONS
.Bl -tag -width Ds
.It Fl c
Compress the files to be uploaded using
.Xr gzip 1 .
This affects all files including piped content and directories.
If specified twice,
.Xr xz 1
will be used rather than gzip.
If used in conjunction with the -g option this decompresses the download
before it's output to stdout.
.It Fl d
Delete the IDs. You can no longer upload files in this mode. If the argument is a URL,
.Nm
will try to extract the ID.
.It Fl e Ar extension
Change the extension used for highlighting. You can also do this if you
have already uploaded the file by appending the extension to the URL.
http://paste.xinu.at/<ID>/bash will change the syntax highlighting to bash.
.It Fl g
Download the IDs and output on stdout. Please take care when using this, as
binary data may cause unexpected results when being output directly to a
terminal. You can no longer upload files in this mode. If the argument is a
URL,
.Nm
will try to extract the ID.
.It Fl h
Display a short help message.
.It Fl t
Upload a tar file containing all files and directories specified on the
command line.
.It Fl v
Display the client version.
.El
.Sh ENVIRONMENT
Some options can be changed by modifying environment variables:
.Bl -tag -width XZ_OPTS
.It Ev GZIP
Assigning GZIP will make the gzip-program treat it's value as if they had been
appended to the command line.
.It Ev XZ_OPTS
The XZ_OPTS environment variable can be used in order to pass additional
options to xz, in case xz is used for compression.
.It TMPDIR
Setting TMPDIR to some directory where
.Nm
create temporary files inside this directory rather than /tmp, if the
underlying
.Xr mktemp 1
program supports it.
.Sh EXAMPLES
.Bl -tag
.It Nm Fl tc Ar directory file
This will create a .tar archive containing the directory and the file and compress
it using gzip and upload one archive.
.It Nm Fl c Ar directory file
This will create a .tar archive containing only the directory. Both (directory and
file) will be compressed using gzip and uploaded independently.
.It Nm Fl cc Ar directory
This will create a .tar archive containing only the directory and compress it using xz.
.It Ic make \&|\&& Nm
This will upload the output of make (stdout and stderr) in csh and similar shells.
