# Building a distribution:
# * update the 'version' variable in ../../Makefile
# * Regenerate version.ads: make -f ../../Makefile version.ads
# * Check NEWS, README and INSTALL files.
# * Check version and copyright years in doc/ghdl.texi, ghdlmain.adb
# * Check GCCVERSION below.
# * Check lists of exported files in this file.
# * Create source tar and build binaries: ./dist.sh dist_phase1
# * su root
# * Build binary tar: HOME=~user ./dist.sh dist_phase2
# * Run the testsuites: GHDL=ghdl ./testsuite.sh gcc
# * Update website/index.html (./dist.sh website helps)
# * upload (./dist upload)
# * CVS commit, tag + cd image.
# * remove previous version in /usr/local
