# Psion's smbclient: samba 3.0.7 with their configure.patch.
#
# "My Network" on the photograph is LinNeighborhood, installed from Psion's
# own linneighborhood_0.6.5-r8_armv5te.ipk. That ipk says
# "Depends: smbclient", and it does all its work by shelling out to
# smbclient, nmblookup and smbmount -- none of which are on the card, so the
# window opens and can browse nothing.
#
# samba_3.0.7.oe (PR=r2) is Psion's recipe. FILES_smbclient is exactly
# smbclient, nmblookup, smbmount, smbumount, smbmnt and ${libdir}/*.dat.
#
# The 3.0.7 release tarball is gone -- samba.org's old-versions now stops at
# 2.2.12, Debian's archive and snapshot skip 3.0.6 to 3.0.8, and the OE,
# Yocto and Gentoo source mirrors have dropped it. The Wayback captures of
# us1/us2.samba.org exist in the CDX index but will not replay. The source
# here is the samba-3.0.7 tag from samba-team/samba, and Psion's
# configure.patch applies to it with all 18 hunks clean and no fuzz, which is
# what says it is the right tree.
#
# A git tag has no generated configure, so autoconf runs first -- which is
# what the recipe's "inherit autotools" does anyway.

#

# trailing semicolon lands alone at the start of the next line and no shell will
# parse it -- "configure: line 3930: syntax error near unexpected token ';'".
# The semicolon is a no-op in the original. It is removed in the source tree,
# in the same spirit as Psion's own hunks; this only checks it has not come back.
