# @sample etc/somefile.conf.sample
|
|
# or
|
|
# @sample file1 file2
|
|
#
|
|
# Where file1 is considered as a sample file and file2 the target file
|
|
#
|
|
# This will install the somefile.conf.sample and automatically copy to
|
|
# somefile.conf if it doesn't exist. On deinstall it will remove the
|
|
# somefile.conf if it still matches the sample, otherwise it is
|
|
# kept.
|
|
#
|
|
# This replaces the old pattern:
|
|
# @unexec if cmp -s %D/etc/pkgtools.conf %D/etc/pkgtools.conf.sample; then rm -f %D/etc/pkgtools.conf; fi
|
|
# etc/pkgtools.conf.sample
|
|
# @exec [ -f %B/pkgtools.conf ] || cp %B/%f %B/pkgtools.conf
