# For official releases, update our build process such that we don't

# need to modify version.conf.
|

#
|
|
# Use tar to append a new or updated version.conf to the archive.

|
|
# constructing a compatible command. BSD tar appears to support inline
|
|
# inline filtering via `-a @- -s /^/wireshark-${VERSION} version.conf`
|
|
# or something similar. GNU tar appears to require that we write to
|
|
# a file and append to it. I'm not sure if we can add a path prefix.
|
|
#
|
|
# Use the 'export-subst' gitattribute along with
|
|
# 'git_description=$Format:...$' in version.conf. export-subst uses
|
|
# 'git log' formatting. I'm not sure if we can build $DESCRIPTION
|
|
# from that.
