ELogList, from SysInternals, can dump the contents of a local or remote event log, and optionally clear the log.

To install the program, just copy the executable to your path. I quote:

Usage: ELogList \[-?\] \[-s\] \[\\computer \[-u username \[-p password\]\]\] \[-n #\] \[-c\] \[eventlog\]                                      -?            Displays the supported options and the units of measurement used for output values.                                     -s            This switch has ELogList print Event Log records one-per-line, with comma delimated fields.                                                   This format is convenient for text searches, e.g. eloglist | findstr /i text,                                                  and for importing the output into a spreadsheet.                                     \\computer    Instead of showing process information for the local system, ELogList will show information                                                  for the NT/Win2K system specified. Include the -u switch with a username and password to login                                                  to the remote system if your security credentials do not permit you to obtain performance counter                                                  information from the remote system.                                     -u username   If you want to view an Event Log on a remote system and the account you are executing in                                                   does not have administrative privileges on the remote system then you must login as an administrator                                                  using this command-line option. ELogList will prompt you for the password without echoing your input                                                  to the display unless you specify the -p switch.                                     -p password   If you specify a user name and omit this switch ElogList will prompt you for a password.                                     -n #          Only display the number of most recent entries specified.                                     -c            Clear the event log after displaying.                                     eventlog      By default ELogList shows the contents of the System Event Log. Specify a different Event Log                                                  by typing in the first few letters of the log name, application, system, or security.
