# This script is meant to be run in an empty directory, although
# it doesn't require it.
#
# This script checks out the latest head revision (by checking it out
# from scratch), checks version information in files, ignores
# files/dirs we don't want to release, tags the source files in cvs,
# generates a ChangeLog and generates the .tar.bz2 file for release.
# Then it uploads this file to upload.sourceforge.net.
#
# It DOES NOT: add the file to the XMLTV project, or email
# announcements, or update www pages, although it reminds you to do
# so :)

**** File $filename uploaded to upload.sourceforge.net

To register this file as part of the release:
  - Go to
< https://sourceforge.net/project/admin/explorer.php?group_id=39046 >
    (login may be required)
  - change folder to xmltv/$opt_version
    click on  files to select appropriate attributes

  Step 1
  ------
  - change status to "Hidden" (for now)
    In the release page, paste the README in as 'release notes', apart
    from the 'changes in this release' section of the README, which
    goes in the 'changelog' box, 
    NOTE: check the 'Preserve my pre-formatted text. ' box
    then click 'Submit/Refresh'
    <page refreshes>

  Step 2
  ------
  - choose $filename, then click
    'Add Files and/or Refresh View' button
    <page refreshes>

  Step 3
  ------
  - set the platform 'Any' and type 'Source bz2'
  - hit 'update' button

  - Toggle 'Status' in Step 1 to 'Active' and hit 'Submit/Refresh' button
    at the bottom of Step 1.
    < how hit 'Summary' button at top of page, you should see release
      show up >

Now update the XMLTV wiki.

Send a release announcement to xmltv-announce\@lists.sourceforge.net,
and update the Freshmeat entry <http://freshmeat.net/projects/xmltv/?topic_id=868>.
