RESTRICT="bindist,mirror,test,strip,fetch"
## bindist   = Distribution of built packages is restricted.
### Downloding installer from leagueoflegends.com == restricted(?)
## mirror    = files in SRC_URI will not be downloaded from the GENTOO_MIRRORS.
### Downloding from non-gentoo source
## test 	 = do not run src_test even if user has FEATURES=test.
### We won't compile, no need to test.
## strip 	 = final binaries/libraries will not be stripped of debug symbols.
### We won't compile, no need to strip. Trying to prevent corrruption.

#DEPEND=""
## We won't compile no need for deps

#BDEPEND=""

PDEPEND=""
## A list of packages to be installed (if possible) after the package is merged. Use this only when RDEPEND would cause cyclic dependencies.
## No need atm

PROPERTIES="interactive"
## A space-delimited list of properties, with conditional syntax support. interactive is the only valid value for now.
## I have no hugging idea what it means and i'm scared that it starts talking at me.
## TIP: See the cdrom eclass for PROPERTIES=interactive examples

#DOCS=""
## An array or space-delimited list of documentation files for the default src_install function to install using dodoc. If undefined, a reasonable default list is used.
## Useless? In theory i can install it with licence or something?.. with PORO document! 

#HTML_DOCS=""
## An array or space-delimited list of documentation files or directories for the einstalldocs function to install recursively.
## Wth is this

 * The ebuild phase 'setup' has exited unexpectedly. This type of behavior
 * is known to be triggered by things such as failed variable assignments
 * (bug #190128) or bad substitution errors (bug #200313). Normally, before
 * exiting, bash should have displayed an error message above. If bash did
 * not produce an error message above, it's possible that the ebuild has
 * called `exit` when it should have called `die` instead. This behavior
 * may also be triggered by a corrupt bash binary or a hardware problem
 * such as memory or cpu malfunction. If the problem is not reproducible or
 * it appears to occur randomly, then it is likely to be triggered by a
 * hardware problem. If you suspect a hardware problem then you should try
 * some basic hardware diagnostics such as memtest. Please do not report
 * this as a bug unless it is consistently reproducible and you are sure
 * that your bash binary and hardware are functioning properly.
