# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         chromium-dev
# Descr:       Open Source version of Chrome Web Browser (Development version)
# URL:         http://www.chromium.org/
# Build needs: - multilib gcc & glibc for compiling the Native Client (64-bit);
#              - libelf with '-D_FILE_OFFSET_BITS=64' added to CFLAGS (32-bit);
#              - ninja.
#              - Internet access (for downloading the nacl/pnacl toolchain bins)
# Needs:       
# Changelog:   
# 39.0.2138.3-1:
#              31/aug/2014 by Eric Hameleers <alien@slackware.com>
# 39.0.2138.3-2:
#              31/aug/2014 by Eric Hameleers <alien@slackware.com>
#              * Fixed the the use of .config/chromium-dev directory name.
# 
# Run 'sh chromium-dev.SlackBuild' to build a Slackware package.
# The package (.txz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'.
