### this list could possibly be sorted better for easier commenting out
### of unneeded groups of compiling components
compiledeps="compiletc.tce advcomp.tce squashfs-tools-4.0.tce"
### list the extensions that will be necessary during build
### including runtime deps and *-devs
#builddeps=""
### list any files that will need to remain writable in the tcz[l,m]
#writeables=""
### if the package includes a configure script list necessary flags here
### ie: "-prefix=/usr/local/"
