# build is in use, but in practice it would be difficult to make the targets

# here usable from a different location than the source tree.

#

# - "make export" is a custom target based on git archive and relevant entries

#   from .gitattributes; it defaults to current sources but can use any git tag

#

# Both types use the TARFILE name for the result, though they generate

# rpmbuild wrapper that translates "--with[out] FEATURE" into RPM macros

#

# Unfortunately, at least recent versions of rpm do not support mentioned

# switch.  To work this around, we can emulate mechanism that rpm uses

# internally: unfold the flags into respective macro definitions:

#

#    --with[out] FOO  ->  --define "_with[out]_FOO --with[out]-FOO"

#

# $(1) ... WITH string (e.g., --with pre_release --without doc)

# $(2) ... options following the initial "rpmbuild" in the command

# $(3) ... final arguments determined with $2 (e.g., pacemaker.spec)

#

# Note that if $(3) is a specfile, extra case is taken so as to reflect

# pcmkversion correctly (using in-place modification).

#

# Also note that both ways to specify long option with an argument

# (i.e., what getopt and, importantly, rpm itself support) can be used:

#

#    --with FOO

#    --with=FOO
