一个可用于linux下的命令行音乐播放器

If you are setting up lynx for DOS for the first time, please see the
separate file "FIRSTIME.TXT". If updating from a previous version, note
that this version is compiled with "Color Styles". You will need to
configure a file called "lynx.lss", specifying how different html
directives will be displayed. Please see the sample lynx.lss file in the
package and the other ".lss" files in the SAMPLES directory.

This is version 2.8.5rel.1 of lynx ported to DOS. This version runs
in DOS and requires a 386 or higher and some sort of packet driver. If
you have a network card installed, use the packet driver specific for
that card. If using a dialup connection, use a ppp packet driver that
simulates a network card. One ppp packet driver that is known to work is
dosppp. The 0.6 pre-beta version is available from:
"http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/net/dosppp/dosppp06.zip"
"http://www.ncf.carleton.ca/ncf/pda/computer/dos/net/dosppp06.zip"
"http://mvmpc200.ciw.uni-karlsruhe.de/~mvmpc9/user/TONI/dosppp/dosppp06.zip"

For help in setting up dosppp on your system, see the setup program
developed by Alfredo Cole, available at:
"ftp://ftp.oldskool.org/pub/tvdog/internet/setup.zip"

Sample configuration files MYPPP.CFG and CHAT.SCR are included. Be 
sure to customize them for your system.

Another ppp packet driver that has been used by some is LSppp. You can
get it at:
"http://members.tripod.com/~ladsoft/lsppp/"

If you just want to run lynx on local files (e.g. to read the help
files), you can run nullpkt.com (usage: "nullpkt 0x60", to unload from
memory: "nullpkt -u"). Don't use this for internet connections. You can't
use bootp for my_ip in WATTCP.CFG when trying to read local files with
nullpkt. See the sample batch file, LYNXLOCA.BAT, for  an example of
how to do this.

Like all DJGPP programs, lynx is a protected mode program and needs a
protected mode interface. You may need to place CWSDPMI.EXE in your
path. Math coprocessor emulation (387) is built into the executable
and should be used automatically if you don't have a math coprocessor.
On occasion, you may need to set "387=N" in your environment to make
this function.

Proxies or external applications can be used if you wish to set them up
and configure them. To use external applications, list them at the end
of lynx.cfg (at "EXTERNAL"). To activate the external application for a
link, place the cursor at the link and press ".", rather than <RETURN>
or <RIGHT ARROW>. Similarly, "," activates the external application
for the current page. Your mileage may vary. If you always want to use
the external application, this can also be set in lynx.cfg, so that
the external application will run when you press <RETURN> or 
<RIGHT ARROW>. To use proxies, enter the proxy address in the proxy
section of lynx.cfg. Don't forget to enter the paths for your local
copies of the STARTFILE and HELPFILE in LYNX.CFG.

To use telnet, you need a file in your path "telnet.bat", which calls a
program such as MSKERMIT or CUTCP, which can do telnet. The appropriate
initialization files need to be configured for your IP address,
nameserver, etc. For MSKERMIT, this is the file MSCUSTOM.INI. For CUTCP
it is CONFIG.TEL. Note that MSKERMIT will not work with epppd.exe from
dosppp05.zip, but will work with the version in dosppp06.zip. It will
work with pppd.exe from dosppp05.zip.

The current mskermit version is 3.15. It is distributed as an update
file to be unzipped on top of version 3.14. You can get it from
"http://www.columbia.edu/kermit/mskorder.html"
"ftp://kermit.columbia.edu/kermit/archives/msvibm.zip" (version 3.14)
"ftp://kermit.columbia.edu/kermit/archives/msk315.zip"

The final version of mskermit 3.16 is available from:
"ftp://netlab1.usu.edu/pub/kermit"

CUTCP which can also interface with tn3270, is available from
"ftp://ftp.cc.umanitoba.ca/software/pc_network/cutcp-b.zip"

To be able to send email from lynx you must create a directory for
your mail-sending files. In general it should NOT be in your PATH. Put
TCPPORT.EXE, X_MAILN.EXE, and MAIL.CFG in that directory. Put WATTCP.MAI
there also, then rename it to WATTCP.CFG. Create a directory under the
mail-sending directory called "spool". Put SENDMAIL.BAT in your path.

MV.EXE is used for changing bookmark files. It should be in your PATH.
CP.EXE should no longer be needed to copy files from your temp directory
to their final path, but is used by the SENDMAIL batch file.

Pushdir and popdir are used in several of the batch files. These
can be commented out, or you can use the pushdir/popdir utilities
of your choice. If you use a TSR pushdir, be sure to put it in your
memory before running lynx, so as to avoid memory conflicts when you
try to close lynx. If you use the batch-file pushdir, be sure to
change "pushdir" to "call pushdir" and do the same for popdir. TSR
pushdir/popdir utilities used to be available from PC Magazine as
v5n10.zip. They are no longer readily available, as PC Magazine has
requested that they be removed from the archive sites, but a search
may find a copy. Non-TSR utilities can be obtained from garbo as
tsbat79b.zip.
"ftp://garbo.uwasa.fi/pc/ts/tsbat79b.zip"

For mouse function with lynx, you must have a DOS mouse driver loaded
and run the TSR "mousekeys" before running lynx. See lynxbat.bat for
suggested parameters to use with mousekeys. With these parameters,
the left key acts as "ENTER" and the right key acts as "LEFT ARROW".
Mousekeys can be obtained from simtel or the author's site as:
"ftp://ftp.simtel.net/pub/simtelnet/msdos/mouse/mousk305.zip"
"ftp://members.aol.com/bretjohn/programs/mousk305.zip"

Local file access looks like this:

file:///c:/
file:///c:/dos
file:///c:/dos/command.com
file:///dev/c/dos/command.com
file://localhost/c:/
file://localhost/c:/dos
file://localhost/c:/dos/command.com
file://localhost/dev/c/dos/command.com

Here are some environment variables that should be set, usually in a
batch file that runs the lynx executable. Make sure that you have enough
room left in your environment. You may need to change your "SHELL="
setting in config.sys. In addition, lynx looks for a "SHELL" environment
variable when shelling to DOS.  If  you wish to preserve the environment
space when shelling, put a line like this in your AUTOEXEC.BAT file also
"SET SHELL=C:\COMMAND.COM /E:4096". It should match CONFIG.SYS, which
should have a line like:
"SHELL=C:\COMMAND.COM /E:4096 /P"

HOME          Where to keep the bookmark file and personal config files.
TEMP or TMP   Bookmarks are kept here with no HOME.  Temp files here.
USER          Set to your login name
LYNX_CFG      Set to the full path and filename for lynx.cfg
LYNX_LSS      Set to the full path and filename for lynx.lss
WATTCP.CFG    Set to the full path for the WATTCP.CFG directory
PWD           Set to the directory from which you are running lynx. This
              is the default directory in which downloaded and printed
              files are saved.
RL_CLCOPY_CMD Command to copy a URL to a "clipboard" file
RL_PASTE_CMD  Command to go to a URL in your "clipboard" file
SSL_CERT_FILE Set to the full path and filename for your file of trusted
              certificates
DJDIR         Set to the full path for the directory under which special
              files are located.

See LYNXBAT.BAT for sample RL_CLCOPY_CMD and RL_PASTE_CMD commands. The
default command to copy a URL to the clipboard file is "CTRL-S". The
default to copy the URL from the clipboard file is "CTRL-Y". Either of
these can be changed by a KEYMAP line in lynx.cfg.

The file LYNXBAT.BAT is a sample batch file to run lynx and to configure
kermit, cutcp, and your wattcp.cfg files using dosppp. Be sure to modify
it for your pathnames and the programs that you are actually using. Note
where forward slashes and backslashes are used (some paths may work with
either). You must also modify SENDMAIL.BAT.

This file is compiled with the wmemu library for 387 emulation.
This is distributed under the GNU license. Source code can
be obtained from any of the DJGPP mirror sites, such as
"http://www.delorie.com/pub/djgpp/current/". Source code for cwsdpmi
and redir is also available from any DJGPP mirror site. The executables
gecho, cp, mv, pwd, and tee are GNU programs with source code available
from any of the GNU archive mirrors such as ftp.gnu.org or the from the
DJGPP mirror sites. Running the executable with the "--version" flag
will tell you which package to get for the source code. To obtain lynx
source code go to "http://lynx.isc.org/" by http and follow the links.
The file is also compiled with the PDCurses library version 2.6 , with
the zlib library, version 1.1.4 and with the bzip2 library, version
1.0.2. The copyright notice for zlib is in the file "zlib.txt" and the
notice for bzip2 is in "bzip2.txt". PDCurses is in the public domain.
The lynx executable is compressed with UPX version 1.22. X_MAILN.EXE
comes from the UKA_PPP distribution by Karl-Heinz Weiss. UKA_PPP is
free for non-commercial use. X_MAILN.EXE is specially licensed free for
commercial or non-commercial use when used in conjunction with lynx. See
the file UKA_PPP.TXT for more details. TCPPORT.EXE is from the WATTCP
distribution by Erick Engelke. It was made available in compiled form by
Karl-Heinz Weiss.

This version is also compiled with openssl-0.9.7d-dev (Dec 10, 2003),
enabling support for https:// URLs. In order to avoid patent problems,
the idea, mdc2, and rc5 algorithms are not used. The copyright notice
for openssl is in the file "openssl.txt". Because this enables strong
encryption, be sure to comply with regulations of the Bureau of Export
Administration if redistributing this from the US. If you are in
another country, please check your laws on use and distribution of
cryptography before using or redistributing this file. The source code
for openssl can be obtained from "http://www.openssl.org/". In order to
make a secure connection, the openssl code needs to be able to verify a
certificate presented by a web site by comparison with a know "trusted"
certificate. The connection is no more secure than the validity of the
"trusted certificates". Be sure to obtain these from a trusted source.
You can extract certificates from the database of another browser (if
you believe that it has not been compromised). To extract from Internet
Explorer, first update the certificate database from the Windows Update
web site, then go to "Internet Options/Content/Certificates/Trusted
Root Certification Authorities", select all (or those you trust), and
then export as a PKCS#7 file. You can then use "openssl pkcs7" to print
the certificates using the "-print_certs" and possibly the "-text"
options. If you are willing to accept less security, you can get a
preassembled file of trusted (by someone) certificates from a well-known
web site. For example, the mod_ssl package contains a file of "trusted
certificates" called ca-bundle.crt in the pkg.sslcfg directory which was
extracted from Netscape Communicator (in March 2000). You can also get a
set of certificates from my website ("http://www.rahul.net/dkaufman/"),
but note that this is not a secure web site, so use these only if
security is not very important.

The default file for the file of certificates is called "cert.pem",
located in the subdirectory "ssl" of your "DJDIR" directory. If you
have the DJGPP development system on your computer, DJDIR is set in the
environment by the DJGPP.ENV file. If you don't have DJGPP installed,
you can set the DJDIR environment variable yourself. Setting DJDIR is
also necessary if you want to use the alternate language files (see the
file "interntl.txt"). If you don't want to set the DJDIR environment
variable and place the file appropriately, you can tell lynx where to
find it by setting the environment variable "SSL_CERT_FILE" to the full
path and filename of the file of certificates.

The default location of the lynx.cfg and lynx.lss files (if the
environment variables are not set) is the "lib" directory under the
directory specified in the DJDIR environment variable.

Special keys, such as ALT keys and function keys can be mapped to
functions in lynx.cfg with KEYMAP statements. Use the numerical value
for the key found in the file PDCURSES.KEY.

If you prefer screen writes via BIOS (significantly slower), set
"PDCURSES_BIOS=TRUE" in your environment.

This version is also compiled with EXEC_LINKS, so that local links to
lynxprog: and lynxexec: URL's can be honored. This is set off by
default, but can be turned on in the option menu and saved to lynx.rc.
It can also be turned on in lynx.cfg by setting:
LOCAL_EXECUTION_LINKS_ON_BUT_NOT_REMOTE:TRUE

This version is compiled with the port of the "DIRED" code to DOS,
allowing local file manipulation. This still has some bugs and may
occasionally freeze the computer, requiring a reboot (occasionally seen
when unzipping an archive if some of the files already exist). Renaming
and moving files should work as is. Compressing and uncompressing files
requires that you have the proper external programs in your path (i.e.
zip, unzip, gzip, tar, compress, zcat, uudecode). Please report problems
with this code to me. The dired menu is accessed by the "f" key.

Internationalization is supported in this version via the "gettext"
method. To use a language other than English, see the separate file,
INTERNTL.TXT. If you use English as your language, you can ignore this
paragraph. Support for internationalization entails a larger binary
and a larger amount of memory needed to run lynx. This probably will
not run well if you have less than 4 Meg of memory. For machines with
3 Meg or less of memory, consider an alternate, smaller binary with
internationalization support removed.

You can now frequently break out of a stuck nameserver lookup or
attempted connection without exiting lynx by using the "z" key. If you
need to immediately break out of a stuck lynx session, use the CTRL-C,
CTRL-BREAK, or ALT-X key combinations to end the lynx session.

This version is compiled with the WATT-32 tcp library, version 2.2
dev.rel.6. Debugging of packets via the WATTCP debugging code is
enabled. See the enclosed sample WATTCP.CFG for details of syntax. To
turn on debugging, invoke lynx with the command-line option "-wdebug".

Please note that "PERSISTENT_COOKIES" (i.e., keeping cookies between
sessions) is now off by default. Change this in lynx.cfg if you want to
keep cookies.

This version is compiled using DJGPP version 2.03 and GCC version 3.3.2.
